copied!<p>I'm not an expert myself, but here some pointers. As far as I understood from Wikipedia, the problem is very likely to be your font. Apologies in advance for the long quotes, but else I could have just linked the 2 Wikipedia articles.</p> <p>Here a part of the section about <strong>ligatures</strong> from the <a href="http://en.wikipedia.org/wiki/Unicode" rel="nofollow">Unicode article</a>:</p> <blockquote> <p><strong>Ligatures</strong></p> <p>Many scripts, including Arabic and Devanagari, have special orthographic rules that require certain combinations of letterforms to be combined into special ligature forms. <strong>The rules governing ligature formation can be quite complex, requiring special script-shaping technologies</strong> such as ACE (Arabic Calligraphic Engine by DecoType in the 1980s and used to generate all the Arabic examples in the printed editions of the Unicode Standard), which became the proof of concept for OpenType (by Adobe and Microsoft), Graphite (by SIL International), or <strong>AAT (by Apple)</strong>.</p> </blockquote> <p>Reading further in the <a href="http://en.wikipedia.org/wiki/Apple_Advanced_Typography" rel="nofollow">AAT (Apple Advanced Typography)</a> article, reveals following information. I recommend reading the whole article.</p> <blockquote> <p><strong>AAT and OpenType in Mac OS X</strong></p> <p>As of Mac OS X 10.5 Leopard, partial support for OpenType is available. The support is currently limited to Western scripts and Arabic (as of 2011). If a font has AAT tables, they will be used for typography. If the font does not have AAT tables but does have OpenType tables, they will be used to the extent that the system supports them.</p> <p><strong>This means that many OpenType fonts for Western or Middle Eastern scripts can be used without modification on Mac OS X 10.5, but South Asian scripts such as Thai and Devanagari cannot. These require AAT tables for proper layout.</strong></p> </blockquote> <p>And later down in the section about font layout:</p> <blockquote> <p>Since AAT operates entirely with glyphs and never with characters, <strong>all the layout information necessary for producing the proper display resides within the font itself.</strong> This allows fonts to be added for new scripts without requiring any specific support from the OS.</p> </blockquote> <p>And last:</p> <blockquote> <p><strong>AAT for Indic scripts</strong></p> <p>For Indic scripts, the only features that are necessary are glyph re-ordering and substitution. AAT supports both of these. As noted above, OpenType fonts for Indic scripts require AAT tables to be added before they will function properly on Mac OS X. Note, however, that this applies only to software dependent upon the system support of OpenType. Programs which provide their own implementation of OpenType will render Indic properly with OpenType fonts. (They may, however, not render Indic fonts with AAT tables correctly.)</p> <p>Mac OS X 10.5 ships with fonts for Devanagari, Gurmukhi, Gujarati, Thai, Tibetan, and Tamil. Fonts for other Indic scripts are available from third parties.</p> </blockquote> <p>Maybe you need to choose a font that explicitly supports Devanagari.</p>
