[sword-devel] NFC and osis2mod

I've been meaning to work on this, but I thought I'd try to point you  
in the right direction since I'm pretty sure I won't have time in the  
next couple days. (I'll be at the UTC meeting at Apple--thinking about  
all things Unicode, but not working on them.) The bugs are almost  
definitely within utf8nfc.cpp. It's never been employed, to my  
knowledge, so it's never been debugged. It's also fairly old and  
should probably be updated to a newer version of the ICU API. (The  
could code work with the existing functions, but it might be best to  
update using some of the copious examples at ICU.)

Your code looks fine to me. My old utf8nfc.cpp code looks a mess.
