[SOLVED] xbian ssh german keyboard support

[p.falk]

Hello,

when I try to access xbian (1.0 beta 2) via ssh I can switch to german keyboard (qwertz) in xbian-config but several keys won't work (ä = ä ö = ö ü = ü ß = ß ). These are necessary for correct filename spelling. Furthermore all the config menus in German miss these characters and have ? instead.
I tried several ways as described in different Xbian/Raspbian/Debian forums, but none did work.

Any hints, esp. for Xbian?

Thanks
Peter
