Many many thanks to everyone who took the time to help me out with the Devanagari ASCII to unicode problem (including one very helpful off-list email). And many many many apologies for my very late reply (I started a new job earlier this week).
I think the conclusion is that I was going about the problem the wrong way---that there is no one-to-one mapping between the Devanagari ASCII font and unicode font. Rather, it is many-to-one. The SIL resources were very helpful. They have a teckit map there for Preeti to unicode (as indicated by Lorna). I have not actually tried it yet; but there is a good chance that it will work or will work with small modification.
