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.
