Incorrect handling of 8 bit characters in passwords.

Description of problem:
usermode, usermode-gtk, xscreensaver, the login prompt all seems to treat
differently passwords who happen to contain 8 bit characters.
Not only that, but we have three types of characters:
- normal (7 bits) characters
- 8 bit characters like i, ` etc
- 8 bit characters typed using dead keys, like j or k
When a password contain one of these characters, some applications refuse to
- some applications work in all cases (login prompt, kdm)
- some applications work in the first two cases, but not in the third (xscreensaver)
- some applications work only in the first case (usermode-gtk)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. change the root passwd to one of 'fo', 'fi', 'fj'
2. login, or launch redhat-config-something, or xscreensaver
3. watch the inability to validate the password.
Of course, the 8 bit characters didn't made it into the bug report:
i is 'e
` is `e
j is ^e
k is "e
Stelian, this works for me with passwd-0.68 (I tried it with Czech
accents like ^c, ^s, etc.) If it's still a problem for you in some
recent release, please reopen this bug and write me ASCII codes of
letters that caused the problem.
No, it is still not solved on a Fedora Core 2, with usermode-1.70-2
BTW, the problem is probably *not* in passwd but in usermode-gtk
(usermode in console works too).
If you want to reproduce:
... in the usermode-gtk window, type the root password, it works
$ su -
New password: Ã© (this is é also known as ascii 0xe9 is ISO8859-1)
... in the usermode-gtk, type the one letter password, it will not work.
Ok, this looks like a GTK problem here, because gtk_entry_get_text() replaces
the 'Ã©' (é character) by '0' in each its occurence within the password
text so I'm tring to fix it.
Maybe it's somehow related to bug 65398.
