I'm speculating, but I wonder if you do a blind form post to change usernames with non-ascii characters whether it will accept them? I think part of the validation by Twitter is done client-side (or so it appears), and that the Twitter databases store screen_name in utf-8 rather than ascii.
I searched my database and found a number of Twitter screen names with spaces. But we have been getting a number of warnings about non-ascii characters... no idea what these are yet (as our database won't hold them as we (wrongly) assumed that they would only be ascii). But I am warn'ing them out and will report what I find. It would be rather crazy to find, say, a single character Chinese Twitter screen name!
