Not so much different character sets, different languages. Different
characters that look the same (like 1 and l). Called homographs (literally
"they look the same"). The Risks digest article is here:
Technically a very simple solution, UTF8 exposes a whole heap of human
engineering issues (the codespace for it is not easy to partition along
language lines, and was never intended to be).
For Jabber though, that's not really an issue. We do have the homograph
problem, but I'd be inclined to let other people worry about it. More
interesting is translating UTF8 names into portable filenames...
