I've done an upgrade from OpenSuSE version 11.1 to 11.2 (text mode).
Since that time, YaST hasn't displayed the interface correctly, e.g. German special characters are crypted, borders aren't displayed correctly. It can't be handled anymore.

Filenames are displayed correctly with 'ls' on the console. So it seems to be only a YaST issue.

Var settings:

I tried also to reinstall YaST without successful change.

How can this problem be fixed?
