Peter, My guru in all things Hindi fonts tells me that the problem lies at the level where encodings are converted into font renderings. Apparently, र् ट is a perfectly correct alternate rendering of the unicode, just not Correct (with a capital C). I have no idea where this happens with MapServer. Thankfully I've never had to create a map with Hindi labels (I would be curious to learn, perhaps off-list, who wants to see maps with Hindi labels), but I too would like to see this resolved.
Hope someone knowledgable chimes in.
