[ft] Combining characters for indian language

[Deepti Chunduru]

Hi,

I need to render indian languages -
devanagari , gurmukhi etc. using freetype.

I am able to display characters corresponding
to unicode values from the unicode chart. 
The problem is displaying combining
characters which require input of a sequence of unicode values.

I pass 1 unicode value to freetype API
at once.

 glyph_index = FT_Get_Char_Index(
face, uni_txt[n]);  // where
uni_txt[] = { 0x0938,0x094d,0x0924,'\0'}

Is there a way by which i can give more
than one unicode value to the API. By doing so, the unicode charmap might
automatically map the sequence to the
appropriate code point and give the combining character.

Is there any other way by which i can
use freetype effectively to render indian languages?

Thanks,
- Deepti
