The charset the UBB uses is embedded in the pages, you can change this via the language editor, but unless it was changed there, it'll have no effect.

As for why it won't allow spaces in the public displayed name (not username) when selected, I'm not sure; but there is another thread going on on these forums that's seeking a fix to spaces in usernames... perhaps that'd help here as well?
