13159,Admin username diacritics silently stripped at install,Jbb,dd32,"1. Fresh install of WP trunk
2. For the admin username, enter some diacritic. For example, '''Jérémie'''
3. All goes well it seems
4. Can't log in with that user

But in the users SQL table, the login name registered is: '''Jrmie'''

Login name should accept most unicode glyphs, especially well unique and used diacritic. A help button at registration should explain the rules of login taxonomy (what's allowed, what's not). And it should never ever alter the login in any way without warning the user.
