Just a wild guess, mind you, but that sounds like toggling keyboard 
drivers or something. As if at a login prompt a different character set was
being delivered than happens later, once you've logged in.

Try logging in as root, and changing the password to something silly 
like 111111. Then try su'ing to root as another user.

Without seeing some of the log/config info that other have requested, 
it's just a guessing game, though.
