Compute SparseBitSet for cmap format 14 subtables. By computing cmap format 14 subtables similar to cmap format 4 or 12, there are following benefits: - FontCollection::hasVariationSelector becomes 70x faster for the worst case, 10x faster for the normal case. - FontFamily::hasGlyph becomes lock-free. - FontCollection::itemize becomes 2x faster than before for some cases. On the other hand, following negative things happen: - Initial FontFamily construction takes 2.5x longer than before, but this only happens in Zygote and should not happen at application launch time. - FontFamily construction from buffer takes longer time than before but it is still around 800µs. - Consumes additionally memory (about 30kB for NotoSansCJK-Regular.ttc of ttc index 0, 2.5kB for NotoColorEmoji.ttf), but this is shared across all applications. No additional memory is necessary if the font doesn't support variation sequences.

Reduce heap memory in minikin. This patch reduces about 73 kB memory. The original SparseBitSet could contain full 32bit integers, but all of that is not necessary for Unicode code points. By reducing the supported range to up to Unicode maximum, U+10FFFF, we can save extra memory. SparseBitSet holds 256-bit sliced pages and indices of them. Previously, we needed to hold up to 2^24-1 pages for keeping 32-bit integers. This CL limits the number of pages to 2^16-1 (65535), so that SparseBitSet only supports 24-bit integers now, but this is sufficient for keeping all Unicode code points. With this change, we can change the index integer type from uint32_t to uint16_t. Bug: 37357593 Test: minikin_tests passes Change-Id: I462cc27927752c942ac5da0bf303a5afb81b87a3

In greedy line breaking, repeat breaks until the line fits Previously, in greedy line breaking, when a line overflowed, we found the best line breaking candidate before it and broke the line there. But we didn't check to see if the remaining part now fits in a line. With this change, we now repeat checking for overflows, and break again until we have no breaking opportunity or the remaining text now fits in a line. Also found an issue with greedy line breaking and keeping the hyphenation edit for the next line which is now fixed. Test: Manual. The issue reported in the bug is now fixed.

Break grapheme clusters after viramas if they end a cluster Previously, we stayed on the conservative side and disallowed any grapheme breaks (and thus cursoring) where a virama was followed by a letter, since we did not know if the virama would be forming a cluster with the letter or not. This created problems with Indic languages with infrequent conjuncts, such as Tamil. Now we use the information in calculated advances to find if a cluster is formed. If there is no cluster, we break the grapheme and allow cursoring after the virama. Test: Unit tests added to GraphemeBreakTests and MeasurementTests. Test: Also manually tested Tamil sequences.

Reduce memory usage of FontCollection. This is 2nd attempt at I9e01d237c9adcb05e200932401cb1a4780049f86. The previous CL was reverted because 8-bit integers were too small to store the indices of mFamilyVec. This CL changes it to 16-bit integers since size_t is still unnecessary large. Theoretically, 32-bit integers are necessary for the indices of mFamilyVec since the size of mFamilyVec can be 0x10EE01. However, in practice, 16-bit integers are enough for the indices of mFamilyVec. The length of mFamilyVec for the system fonts is 2084. Even if the developers load their own very large fonts, it can only increase the number of elements in mFamilyVec to at most 0x10FF. As the result, memory usage of the FontCollections for the system fonts decreases as follows. 64-bit process: before: 398,264 bytes, after: 282,568 bytes (-115,696 bytes) 32-bit process: before: 199,132 bytes, after: 149,548 bytes (-49,584 bytes) Bug: 33562608 Test: Verified Emoji and CJK characters are present.

Correct hyphenation for various complex cases This adds better support for Arabic script languages, Armenian, Catalan, Hebrew, Kannada, Malayalam, Polish, Tamil, and Telugu by adding various hyphenation types and edits appropriate for the locales. For Arabic script languages, soft hyphens act transparently with regard to joining: If a line is broken at a soft hyphen where the two characters around the soft hyphen were joining each other before, they will continue to appear joining if the line is broken at the soft hyphen and a hyphen glyph is inserted. This is needed for Central Asian languages such as Uighur. For Armenian, U+058A ARMENIAN HYPHEN is used for line breaks caused by either automatic hyphenation or soft hyphens. For Catalan, nonstandard line breaks are implemented for "l·l", which hyphenates as "l-/l". For Polish, when there is a line break at a hyphen, the hyphen is repeated at the next line. For the South Indic languages, when breaks happen due to soft breaks or automatic hyphenation, no visible hyphen is inserted, although a penalty is added. For Hebrew, support for using U+05BE HEBREW PUNCTUATION MAQAF has been implemented, but it's turned off pending confirmation of desirability. Also, hard hyphens, which previously had no penalty added for breaking the line after them, now have the same penalty as an automatic or soft break, with the difference that no hyphen is inserted when they break. Finally, some bugs have been fixed with hyphenating multiscript and multi-font words.

Add U+202F NARROW NO-BREAK SPACE to the sticky white list Mongolian fonts need to shape across U+202F NARROW NO-BREAK SPACE (NNBSP). But if the first font in the fallback chain supports NNBSP, it would break Mongolian shaping since the text would be broken into three font runs. By making NNBSP sticky, we make sure Mongolian text is kept in one font run and is shaped properly. See http://www.unicode.org/L2/L2017/17036-mongolian-suffix.pdf for background. The proposed character in the proposal was not accepted for encoding by the Unicode Techincal Committee, but the document explains in more detail why this change in needed.

Here is the original commit message of reverted change. This lays the groundwork for variation settings support.

This method should be removed once http://b/28119474 is fixed. Here is original commit message of reverted change. This lays the groundwork for making SparseBitSet serializable. FontFamily.addFont is only used when the FontFamily is constructed. Thus, instead of calling FontFamily.addFont multiple time, passes Font list to the constructor. By this change, FontFamily can be immutable now. By making FontFamily immutable, We can create FontFamily with pre-calculated SparseBitSet.

Introduce createCollectionWithVariation. This lays the groundwork for variation settings support. Since we should regard different variations of a font as different fonts, we need to create new typefaces. To reuse the same instance of MinikinFont, as much as possible, FontFamily::createFamilyWithVariation now reuses an existence instance, while incrementing the reference count.

Fix GraphemeBreak test failures. GraphemeBreak.tailoring/GraphemeBreak.genderBalancedEmoji start failing after ICU update to 58. The failure is around Rule GB9 in Unicode Standard Annex #29. GB9 forbids breaks before extending characters and before ZWJ. However the implementation in minikin only checks for extending characters. It used to work with Unicode 8.0 since ZWJ had the Grapheme_Cluster_Break property of Extend in Unicode 8.0 but it no longer has that property in Uniocde 9.0. Thus, we need to check for ZWJ explicitly. At the same time, this removes manually added PREPEND characters case from tailoredGraphemeClusterBreak which is already supported in ICU 58.

Reduce memory usage of FontCollection. Since switching to 64-bit devices, size_t is now a 64-bit integer. FontCollection::Range uses two size_t integers but they just point to an index in mFamilies. To reduce the memory usage, this CL changes the size_t integers to uint8_t. The maximum size of each integer in Range is the size of FontCollection::mFamilies. The largest this can go is the system font list plus a user defined family, which has 91 families. So an 8-bit integer should be enough. With this change, about 84 KiB of memory will be saved per font collection. Since eight font collections are created during bootstrap, about 670 KiB of memory will be saved with this CL. Bug: 33562608 Test: Ran FontCollection.collectionAllocationSizeTest on a 64-bit device. On my Nexus 5X, it changed from 327358 to 241342. Change-Id: I9e01d237c9adcb05e200932401cb1a4780049f86

Tune line breaking for justification Add an "mJustified" for justification, and tune the line breaking to produce good results. Major differences for fully justified text include: - Space can be shrunk in justified text. - Hyphenation should be more aggressive in justified text. Also adds a penalty for the last line being very short. This is tuned to be more aggressive for ragged right than for justified text. This is based on a patch by Raph Levien (raph@google.com).

In addition, a match in subtag has a higher priority than a match in script. The score levels are divided into 5 score levels and the limit of the number of font languages is changed to 12 from 17.

Fix lookup order for VS in itemization. This is partial revert of Iced1349e3ca750821d8882c551551f65bb569794. Due to sorting of target family vectors, the font family order from XML settings file is broken. Making unique operation stable doesn't fix the issue completely since some font families are appended for the fallback which also breaks the original order. By this change, itemization becomes 3x slower than before if variation selector is appended. Bug: 29585939 Change-Id: I7c1a8a57f04111a30cd41a5cd5bec25fcfb3972e

Rename libicuuc-host/libicui18n-host to libicuuc/libicui18n These modules can be named the same between the target and host libraries, which simplifies references to them, particularly in Soong. To prevent accidentally loading the system copy of the library, we still rename the installed name to be libicu*-host.so. But modules do not need to know that in order to build against them.

Thus always lookup the glyph for the code point before and after zwj as if they have a U+FE0F variation selector. Bug: 30056627 Change-Id: I03958a92337eaba4a8dd9c5be824b2665aa4a103

Add some gender balanced components in to the sticky whitelist. FEMALE SIGN(U+2640), MALE SIGN(U+2642), StAFF OF AESCULAPIUS(U+2695) will be used as the ZWJ sequenced in gender balanced emoji sequence. To be in the same run with ZWJ, mark these emoji as sticky chracters. With this fix, Female police officer sequence will be shown correctly regardless of VS16.

Fix minikin_unittests This CL fixes following test cases in minikin_tests - FontFamilyTest.hasVariationSelectorTest - HbFontCacheTest.getHbFontLockedTest - HbFontCacheTest.purgeCacheTest For the fix of FontFamilyTest.hasVariationSelectorTest, removing virtual from GetUniqueId() in MinikinFont. After [1], MinikinFont's destructor started calling purgeHbCache() which calls virtual method, MinikinFont::GetUniqueId(). Fortunately, the SkTypeface::uniqueID() returns just internal value, so we can store it at the construction time and use it instead of calling SkTypeface::uniqueID() every time. This patch also changes purgeHbFont to purgeHbFontLocked, as all uses of it were already under global mutex. This change avoids deadlock on explicit unref, as when invoked by a Java finalizer from the Java object that holds a reference to the font. Some of the tests needed to change to using the ref counting protocol rather than explicitly destructing font objects, as well.

Avoid copying of font table data The hb_font_t object holds on to tables of font data, acquired through the MinikinFont::GetTable interface, which is based on copying data into caller-owned buffers. Now that we're caching lots of hb_font_t's, the cost of these buffers is significant. This patch moves to a different interface, inspired by HarfBuzz's hb_reference_table API, where the font can provide a pointer to the actual font data (which will often be mmap'ed, so it doesn't even consume physical RAM).

Support multiple locales for font language settings. Some fonts support multiple scripts, for example, some fonts for Korean supports not only "Kore" but also "Jamo". To select fonts based on their multiple languages, this CL introduces the following changes: - Compares all languages of the font family and use the maximum score for font selection. - Even if each language of the font family doesn't support the requested language, the font get score of 2 if the requested font is covered by all of the languages of the font family. For example, the font for "ko-Hang,ko-Hani" gets score of 2 for the requested language "ko-Kore". Bug: 26687969 Change-Id: I7f13b51464c9b01982bb573251d77052b9ddbd70

Try putting combining marks in the same font run Indic combining marks, when combined with a common character such as a hyphen or a dotted circle, used to get rendered in a different font due to the greedy algorithm used in determining runs, which resulted in the base character and the combining mark getting rendered in separate font runs, resulting in a dotted circle appearing in phrases such as "100-ാം" (0031 0030 0030 002D 0D3E 0D02). This change makes combining marks change the font run of the base character if the base character is supported in the same font as the combining mark, similar to the support for emoji modifiers and the combining keycap.

Current (Unicode 8) logic does indicate a line break, so we override the results of the ICU line break iterator.

Add penalty for breaks in URLs and email addresses Recent changes have added special cases for line breaks within URLs and email addresses. Such breaks are undesirable when they can be avoided, but at other times are needed to avoid huge gaps, or indeed to make the line fit at all.

Improve Paint.measureText and Paint.hasGlyph for variation sequences. Before this patch, the font fallback chain iterated all installed font families if a variation selector was specified. This CL narrows down the range of iteration. To decide the font family for the variation sequence, we need to search for both the variation sequence and its base code point. The new range of the iteration is a union of them. With this change, the running time of Paint.hasGlyph for the variation sequence improves 50% and the running time of Paint.measureText for the variation sequence improves 40% for the large text case on Nexus 6 userdebug.

Refine hyphenation around punctuation Implement a WordBreaker that defines our concept of valid word boundaries, customizing the ICU behavior. Currently, we suppress line breaks at soft hyphens (these are handled specially). Also, the new WordBreaker class has methods that determine the start and end of the word (punctuation stripped) for the purpose of hyphenation. This patch, in its current form, doesn't handle email addresses and URLs specially, but the WordBreaker class is the correct place to do so. Also, special case handling of hyphens and dashes is still done in LineBreaker, but all of that should be moved to WordBreaker.

Improve Paint.hasGlyph performance by caching hb_font_t It turned out that hb_font_t creation is not a lightweight operation. Especially, Paint.hasGlyph creates hb_font_t for all existing fonts every time. To improve the performance, cache hb_font_t instead of hb_face_t. Note that to calculate horizontal advance, MinikinPaint needs to be associated with hb_font_t by calling hb_font_set_funcs. With this patch, hb_font_set_funcs may be called multiple times for the same hb_font_t object. However this is not an issue since MinikinPaint is unique during layout.

Disable unsigned integer overflow sanitization until libc++ is fixed. Bug: http://b/26781196 Bug: http://b/25884483 Bug: http://b/26432628 Although this issue was first only manifesting on Fugu, it now affects N9 and N6p as well. This change disables unsigned overflow sanitization on all platforms. The real fix for libc++ (r257368) can't be committed until we have updated Clang at least one more time.

Introduce multiple language based font fallback. The motivation of this CL is enhance the font fallback score design to support multiple language font fallback. This CL contains following changes: - Break language based font score into two: script-based score and primary-language-based score. - The primary-language-based score is 0 if the script-based score is 0. If the script-based score is not 0 and the primary language is the as same as the requested one, the font gets an extra score of 1. - The language score gets a higher multiplier for languages higher in the locale list.

Fix race condition in Paint.hasGlyph() The caller of FontFamily::hasVariationSelector needs to acquire the lock before calling it, but FontCollection::hasVariationSelector didn't acquire the lock. This caused a race condition. This CL fixes this race condition. Also, it turned out that assertMinikinLocked didn't assert even on eng or userdebug device. This CL enables assertion on eng and userdebug device since this assertion must be treated as bug. BUG: 26323806 Change-Id: I9c4b1e1f09c6793e387fbdb8bb654cc0a13c65d5

Save all kind of script tags into FontLanguage. This is 2nd attempt of I8df992a6851021903478972601a9a5c9424b100c. The main purpose of this CL is expanding FontLanguage to be able to save full script tag. Previously, FontLangauge kept only limited script tags. With this CL, FontLanguage keeps all script tags. This CL contains the following changes: - FontLanguage changes: -- Moved to private directory not to be instantiated outside of Minikin. -- Removed bool(), bits(), FontLanguage(uint32_t) methods which are no longer used. -- Change the FontLanguage internal data structure. -- Introduces script match logic. - FontLanguages changes: -- Moved to private directory not to be instantiated outside of Minikin. -- This is now std::vector<FontLanguage> - FontLanguageListCache changes: -- Now FontLanguageListCache::getId through FontStyle::registerLanguageList is the only way to instantiate the FontLanguage. -- Normalize input to be BCP47 compliant identifier by ICU.

Avoid integer overflows in parsing fonts A malformed TTF can cause size calculations to overflow. This patch checks the maximum reasonable value so that the total size fits in 32 bits. It also adds some explicit casting to avoid possible technical undefined behavior when parsing sized unsigned values.

Search all families instead of using mRanges for variation sequence. To optimize the font family search, mRanges is used for narrowing down the search range. However, mRanges is constructed from format 4 or format 12 entries. So, if the font supports a variation sequence but doesn't support the base character of the sequence, the font may not be listed in mRanges. The proper way to fix this issue is using format 14 subtable information for mRanges construction. However, this is not a trivial work since currently we rely on HarfBuzz for variation sequence lookup and it doesn't provide any API for retrieving coverage information. Thus, as the quick fix, iterate all font families in font fallback chain if the variation sequence is specified. Change-Id: I278da84be8fb8f553590e2e42ed450b7e4a34eca

Resolve glyph ID by HarfBuzz function. Currently codepoint to glyph ID resolution is done through MinikinFont interface. To support variation selector, use HarfBuzz API instead of calling this interface since one of its implementation Skia doesn't support variation selector. On the other hand, we don't want to get glyph horizontal advance values by HarfBuzz since HarfBuzz doesn't return correct values when the hinting is active. Thus, use ot_font as a parent font and override glyph_h_advance/glyph_h_origin functions as is. With this change, MinikinFont::GetGlyph is no longer necessary but not removing in this CL for easy reverting since removing interface requires multi-repository commit. This is a base work of b/11256006 and this patch doesn't provide any user visible changes. Bug: 11256006 Change-Id: I061172c0b674bb649ce8bc013ffecf38708bdc41

Improve fallback where explicit variant is not given In computing scores for which fallback font to choose, a match of a variant given explicitly in the xml config file scores higher than a family with no explicit variant. One consequence is that U+2010 HYPHEN is chosen from the Naskh Arabic font in the fallback case. This patch scores families with no variants as a match (effectively the same as if the xml file specified both variants). Thus, it will choose the first matching font (Roboto), which is a better choice. This patch also revises the list of "sticky" characters to include various hyphens, so Arabic (and potentially other scripts) text that includes hyphens can access the script-specific variants matched to the underlying text.

Consistently apply break opportunities in text spans It's essential not to apply a break opportunity within a replacement span, otherwise things can happen such as displaying the span twice. The old code tested this case based on zero-width characters. However, this test was both imprecise, and also in some cases read uninitialized values from the mCharWidths array, which in turn led to inconsistent line breaking of the same text. This patch applies all line break opportunities (as identified by ICU) within text (as opposed to replacement spans), and also applies break opportunities at the beginning and end of replacement spans, but avoids breaks within a replacement span.

Previously, automatic hyphenation blindly took almost every line breaking opportunity as a word break, so words like "low-budget" were treated as two separate words, "low-", and "budget", each automatically hyphenated.

Allow clusters to start with zero-width characters The logic in getRunAdvance() assumed that any zero-width character was part of the preceding cluster, which is valid most of the time.

Separate additional penalty for last line with hyphen A recent change added a penalty for a hyphen at the last line break, which is visually undesirable.

Use ASCII HYPHEN-MINUS when there's no HYPHEN in the font. Previously, we just assumed the font in use had a U+2010 HYPHEN character, resulting in a tofu (or an empty space) being shown when U+2010 was not supported in the font used to render the hyphenated word. Now we try to fallback to U+002D HYPHEN-MINUS, which has a very good chance of being available in at least any Latin font. We still show a tofu when neither character is supported, to intentionally alert that something is missing.

Increase hyphenation penalty for short last line Tuning for hyphenation parameters. We discourage hyphenation on the last line, but offset this penalty by also applying a penalty for each line, which optimizes for minimizing the number of lines. Thus, when hyphenation can reduce the number of lines, it increases the chance they're used. There's probably more tuning and refinement that can be done, but testing suggests that the tunable parameters are appropriate. Bug: 20883322 Change-Id: Ida7eaf8aced109e426694f5a386924a842d29c4b

Don't include trailing newline in width for line breaking In a paragraph with a trailing newline, the width of the newline character was included in the line width for breaking purposes, basically as if it were a non-breaking space. This caused a discrepancy, where Layout.getDesiredWidth() suggested that the text would fit in a single line, but StaticLayout would break it because of the added width of the newline character. The proposed fix is simply to consider newline to be a space that disappears at the end of a line. Bug: 20152308 Change-Id: I539574c5b8ea892c8ed6aca6c59e90ccdf74a680

Add hyphenation to line breaking This patch adds hyphenation using the Liang hyphenation algorithm, similar to TeX. It also improves the optimized line breaker so that it works correctly and efficiently even when the line width is not constant (there is a specialization for constant width, which is probably worthwhile, but performance TODOs remain). Still to be done: * hyphenator has many shortcuts, only tested with English * interaction between punctuation and hyphenation is problematic Change-Id: I2d94a1668ebc536398b7c43fcf486333eeb7c6aa

Add LineBreaker to Minikin This patch adds a LineBreaker class to Minikin, which will be used for computing line breaks in StaticLayout. The version in this patch contains basically the same functionality that existed before, but hopefully better performance and an interface that's suitable for more sophisticated paragraph layout. Note that this version contains a high quality strategy, which mostly works but doesn't respect varying line width. Change-Id: I02485d58b1e52856296a72cdd4efd963bc572933

Fix Layout initialization in the skipCache path C++ local var initialization always tricks me. Previously, Layout didn't have a constructor, which meant that defining it on the stack left mAdvance uninitialized. This was not an issue when we were doing "new Layout()", since that invokes zero-initialization, but was an issue for the skipCache path that was allocating layout on stack by just "Layout l" instead of "Layout l = Layout()". To avoid surprises, add a constructors that clears everything. Also adds reset() method to reset the layout for reuse. Change-Id: I3e02f00da9dd7d360abe13f63c310f6882292d0a

Assign non-coverage font runs to base font When a run has no cmap coverage in any font, use the base font. Most of the time, this will cause rendering of the .notdef glyph, which is preferable to displaying nothing. In some cases, Harfbuzz may be able to decompose the characters (not in the cmap) to ones that are, in which case we'll render those, as long as they're in the base font.

Make font runs less sticky Fixes b/15734816 In the text "Wi-Fi", "-Fi" appears bolder than "Wi" The problem was caused by "stickiness" in choosing fonts, where layout would prefer using a font used for preceding characters as long as it mapped the following characters in a run, in favor of the "best match" rules. This patch adds a whitelist for making the stickiness more conservative, only applying it for characters necessary for correct shaping (ZWJ and ZWNJ in particular) and basic punctuation, where it is desirable to match the style of the preceding text.

Caching for layouts and harfbuzz faces This patch adds caching for both layouts and for HarfBuzz face objects. The granularity of the cache for layouts is words, so it splits the input string at word boundaries (using a heuristic). There are is also some refactoring to reduce the amount of allocation and copying, and movement towards properly supporting contexts. The size of the caches is a fixed number of entries; thus, it is possible to consume a large amount of memory by filling the cache with lots of large strings. This should be refined towards a scheme that bounds the total memory used by the cache. This patch fixes bug 15237293 "Regression: Measure performance is significantly slower with minikin".

Do BiDi algorithm for text layout This is a fix for bug 15130102 "Language name for Hebrew displayed the wrong way around on keyboard". This patch extends the previous BiDi support (when the direction for the entire string was given by the caller) to run the BiDi algorithm (provided by ICU) over the string to break it into BiDi runs. Thus, it handles mixed LTR and RTL strings in a single layout, and also respects heuristics for inferring the paragraph direction from the string.

Initial BiDi support This patch contains a very basic implementation of BiDi. It respects the BiDi flags passed in as an explicit parameter (through the "-minikin-bidi" pseudo-CSS property), but doesn't yet do its own BiDi run detection. It also takes some shortcuts (marked as TODO) that are based on reasonable assumptions of the current font stack, but not universally valid. Even with these shortcomings, it seems to display RTL text from TextView correctly. Change-Id: I223433923c4eb06f90c0327e86bfbe0aff71d4f5

A basket of features: itemization, bounds, refcount This patch improves script run itemization and also exposes metrics and bounds for layouts. In addition, there is a fair amount of internal cleanup, including ref counting, and making the MinikinFont abstraction strong enough to support both FreeType and Skia implementations. There is also a sample implementation using Skia, in the sample directory. As part of its functionality, his patch measures the bounds of the layout and gives access through Layout::GetBounds(). The corresponding method is not implemented in the FreeType-only implementation of MinikinFont, so that will probably have to be fixed. Change-Id: Ib1a3fe9d7c90519ac651fb4aa957848e4bb758ec

Initial commit of Minikin library This is the initial draft of Minikin, a library intended to perform text layout functions. This version does basic weight selection and font runs for scripts, and also has a simple renderer for drawing into bitmaps, but is lacking measurement, line breaking, and a number of other important features. It also lacks caching and other performance refinements. Change-Id: I789a2e47d11d71202dc84b4751b51a5e2cd9c451
