Using non latinic characters to log in

a client reports that they cannot use non-latinic characters to log in. Has this been a problem with other sites? How do we get around this?

Thanks,

Dan

You don't - usernames can only include alphanumeric characters, underscores, and minus (-); no special or foreign characters are permitted. Otherwise, things start breaking. Users can login with their email address as well, so perhaps renaming the login field to ask for their Email instead would be better.
