Error after upgrading

Hi !
I upgraded my openSUSE 11.2 to openSUSE 11.4 . Unfortunately after the upgrade the OS does not recognize many characters at many places . For eg :- In YaST , everything is square boxes as if the character set weren’t present . Moreover , every theme has same font at every place i.e. Sans Serif . After the upgrade, the graphics have become worse . Please help out ,. I’m using KDE environment . Hardware is : Core i5/4GB .
