    A password is a string of bytes, not characters.

    As I wrote previously:

    If a password contains non-ASCII characters, the encoding used when
    entering a password must match the encoding which was used when the
    password was set. E.g. if you set your password from a terminal which
    uses ISO-8859-1, then try to enter it in a GDM dialog which uses
    UTF-8, the password won't be recognised.
