Punctuation error in Hindi MOGRT files

Hi,

Is there any way to use vernacular language with MOGRT files? When I try, the fonts render with plenty of errors in punctuation. I'm facing this for Hindi, and I believe it's there for other Indian languages as well. I have tried this with Adobe fonts. I have already changed the Graphic preferences to South Asian languages and enabled ligatures for Hindi, but the proplem persists.
Would be grateful for any leads.
