OK, it's stored in UTF-8, which supports an awfull lot of
characters... But IPA seems to protect us:
ipa user-add --first="ßuper" --last="üser" ßuperüser
ipa: ERROR: invalid 'login': may only include letters, numbers, _, -,

As I said, POSIX systems are the limit, thus IPA limits you to have uid
as POSIX standard requires.
