I am currently using the iPhone SDK to create an app that utilizes Indic scripts. However, the iPhone has issues with rendering certain glyphs in many Indic scripts. For example:
प + ् + र = प्र
or
ਕ + ੍ + ਰ = ਕ੍ਰ
When you type this on a Mac (or Windows) the computer will automatically render the three characters into the one glyph (प्र - In Unicode it is still represented as three characters however). Because the iPhone doesn't support AAT (Apple Advanced Typography) or advanced OpenType features it renders the characters as three separate which becomes unreadable in many cases. I'm thinking there should be a way to hard code in Objective-C to ensure that every time the three characters show up in a UILabel they should render a certain glyph from the Arial Unicode MS (built-in) font instead. I do not mind using undocumented APIs to accomplish this.
