Yast on dedicated server is not proprerly displayed with gnome-terminal

Hello, on my dedicated server runs suse 10.0. When I log into the dedicated server with remote console and start yast it all works very good with the KDE-Konsole. But when I start yast in the gnome-terminal, there are just strange letters displayed, like ÄÄÄÖÄÜÜÖÖÄÄÄÜÄÄÄÜ or similar. Is it a setting of gnome-terminal which has to be changed? Greets Ruediger
