Do EAI MTAs do this sort of langauge-sensitive mapping on incoming non-ASCII addresses? There's no reason they can't, and the advantages of doing so are obvious. I can see problems where systems are large enough to be used by recipients that speak multiple languages, but I'd think that it can usually guess what language a mailbox is in, or it can just ask when the address is created.
