I know, but as Xft uses freetype2, you would get into trouble trying to 
intermix this with freetype1. The option you have is to copy the code from 
freetype1 over.

Possible. I would need 1-2 quiet weeks to evaluate this.

That's already possible. Just set your font family to any indic true type font 
(provided it has a Unicode mapping).
