XLockupString() does (in contrary to the documentation) respect the
locale-settings. I startet xev with three different LC_ALL settings and
pressed the euro-key each time (see below).
You're right, my second patch only works for utf-8 charset which can't
be assumed. But the first patch will work always as long as
XLockupString() and pam or /etc/shadow use the same charset and the
charset has not more than four bytes per char (As far as I know no such
charset is in use). The first patch won't break any existing
functionality.
If this problem isn't going to be solved, I think I should file a bug to
use gnome-screensaver as default since a password dialog that doesn't
support all common characters is simply broken.
