latin 2 character-set with xterm

Hi,

We have problems with the latin 2 Character-set with xterm.

We have installed SunRay-Server with Solaris 8. Our Thinclients use hu- and cz-keyboards. I have set the right local-settings and xmodemaps. If I use the dtterm all is running fine. As soon as I use the xterm, it cannot display the latin2 characters (e.g. ) although the local-settings right.
What can I do?

many thanx
