VNC - international characters

Hi,

SuSE 11.0 x86_64, default VNC server.
Client: RealVNC, TightVNC, UltraVNC under M$ XP.
Language: Hungarian (both XP and SuSE).
GUI: KDE3.5 or IceWm.

The Hungarian special characters (á,é, ó, etc.) can’t be seen in terminal window (xterm, Konsole, etc.)
The other characters in Hungarian layout (,|,@, …etc.) work.

Any solutions?

TIA,
