Question about wrong characters.

[Ra�l Ib��ez]

Hi.   I've installed RH8 with a spanish keyboard layout and english lenguage.   When I use the terminal in the local comp. the spanish characters (�, �, � ...) work OK, but when I connect by a ssh connection or even using the gvim app. these characters are bad shown.   What can I do to resolve this problem ? Where is my fault ?   Thank you.   Raul.
