Since there is no way of storing encoding information along with
the username, any attempt to use multibyte will result in display
issues on multi-locale environments; whether or not this is
satisfactory is up to the users in question.

The OS should 8 bit clean wrt usernames just as it is for filenames;
the same problems exist there.
