It is most 182ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * useful for use with legacy data formats and legacy display technology 192ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * (simple terminals). All operations are performed on Unicode characters.</p> 202ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * 212ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * <p>Text-based shaping means that some character code points in the text are 222ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * replaced by others depending on the context. It transforms one kind of text 232ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * into another. In comparison, modern displays for Arabic text select 242ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * appropriate, context-dependent font glyphs for each text element, which means 252ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * that they transform text into a glyph vector.</p> 262ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * 272ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * <p>Text transformations are necessary when modern display technology is not 282ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * available or when text needs to be transformed to or from legacy formats that 292ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * use "shaped" characters. Since the Arabic script is cursive, connecting 302ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * adjacent letters to each other, computers select images for each letter based 312ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * on the surrounding letters. This usually results in four images per Arabic 322ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * letter: initial, middle, final, and isolated forms. In Unicode, on the other 332ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * hand, letters are normally stored abstract, and a display system is expected 342ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * to select the necessary glyphs. (This makes searching and other text 352ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * processing easier because the same letter has only one code.) It is possible 362ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * to mimic this with text transformations because there are characters in 372ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * Unicode that are rendered as letters with a specific shape 382ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * (or cursive connectivity). They were included for interoperability with 392ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * legacy systems and codepages, and for unsophisticated display systems.</p> 402ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * 412ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * <p>A second kind of text transformations is supported for Arabic digits: 422ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * For compatibility with legacy codepages that only include European digits, 432ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * it is possible to replace one set of digits by another, changing the 442ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * character code points. These operations can be performed for either 452ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic 462ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * digits (U+06f0...U+06f9).</p> 472ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * 482ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * <p>Some replacements may result in more or fewer characters (code points). 492ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * By default, this means that the destination buffer may receive text with a 502ae130017183d2f66d55bf0ca51f8da3294644fdNeil Fuller * length different from the source length.
