// Bidi stands for support for languages with a bidirectional script.
|
||
|
|
//
|
||
|
|
// Usually Unicode Bidi Algorithm used by OS platform (and web browsers) is capable of properly transforming
|
||
|
|
// Bidi text and as a result it is adequately displayed on the screen. However, in some situations,
|
||
|
|
// Unicode Bidi Algorithm is not invoked or is not properly applied. This may occur in situation in which software
|
||
|
|
// responsible for rendering the text is not leveraging Unicode Bidi Algorithm implemented by OS (e.g. dojox.GFX renderers).
|
||
|
|
//
|
||
|
|
// Bidi engine provided in this class implements Unicode Bidi Algorithm as specified at:
|
||
|
|
// http://www.unicode.org/reports/tr9/.
|
||
|
|
//
|
||
|
|
// For more information on basic Bidi concepts please read following article:
|
||
|
|
// "Bidirectional script support - A primer" available from:
|
||
|
|
// http://www.ibm.com/developerworks/websphere/library/techarticles/bidi/bidigen.html
|
||
|
|
//
|
||
|
|
// As of February 2011, Bidi engine has following limitations:
|
||
|
|
// 1. No support for following numeric shaping options:
|
||
|
|
// H - Hindi,
|
||
|
|
// C - Contextual,
|
||
|
|
// N - Nominal.
|
||
|
|
// 2. No support for following shaping options:
|
||
|
|
// I - Initial shaping,
|
||
|
|
// M - Middle shaping,
|
||
|
|
// F - Final shaping,
|
||
|
|
// B - Isolated shaping.
|
||
|
|
// 3. No support for source-to-target or/and target-to-source maps.
|
||
|
|
// 4. No support for LRE/RLE/LRO/RLO/PDF (they are handled like neutrals).
|
||
|
|
// 5. No support for Windows compatibility.
|
||
|
|
// 6. No support for insert/remove marks.
|
||
|
|
// 7. No support for code pages (currently only UTF-8 is supported. Ideally we should convert from any code page to UTF-8).
