I downloaded xmbdfed and a Devanagari font and looked at the map. The characters defined in Unicode are at 0900-09ff which is the Devanagari code page. The others (half-letters and ligatures) are at e900-e9ff which is in the private use area. I don't know if they will be at the same place in all Devanagari fonts, but at least I know where they are in this one. phma
