| 10 | // Bidi stands for support for languages with a bidirectional script. |
|---|
| 11 | // |
|---|
| 12 | // Usually Unicode Bidi Algorithm used by OS platform (and web browsers) is capable of properly transforming |
|---|
| 13 | // Bidi text and as a result it is adequately displayed on the screen. However, in some situations, |
|---|
| 14 | // Unicode Bidi Algorithm is not invoked or is not properly applied. This may occur in situation in which software |
|---|
| 15 | // responsible for rendering the text is not leveraging Unicode Bidi Algorithm implemented by OS (e.g. dojox.GFX renderers). |
|---|
| 16 | // |
|---|
| 17 | // Bidi engine provided in this class implements Unicode Bidi Algorithm as specified at: |
|---|
| 18 | // http://www.unicode.org/reports/tr9/. |
|---|
| 19 | // |
|---|
| 20 | // For more information on basic Bidi concepts please read following article: |

| 24 | // As of February 2011, Bidi engine has following limitations: |
|---|
| 25 | // 1. No support for following numeric shaping options: |
|---|
| 26 | // H - Hindi, |
|---|
| 27 | // C - Contextual, |
|---|
| 28 | // N - Nominal. |
|---|
| 29 | // 2. No support for following shaping options: |
|---|
| 30 | // I - Initial shaping, |
|---|
| 31 | // M - Middle shaping, |
|---|
| 32 | // F - Final shaping, |
|---|
| 33 | // B - Isolated shaping. |
|---|
| 34 | // 3. No support for source-to-target or/and target-to-source maps. |
|---|
| 35 | // 4. No support for LRE/RLE/LRO/RLO/PDF (they are handled like neutrals). |
|---|
| 36 | // 5. No support for Windows compatibility. |
|---|
| 37 | // 6. No support for insert/remove marks. |
|---|
| 38 | // 7. No support for code pages (currently only UTF-8 is supported. Ideally we should convert from any code page to UTF-8). |
