You don't mention what application you are using. Sometimes the language
settings there could give you grief. I just upgraded to 11.10 and when I ran
Reconq browser on Kubuntu for the first time and it was in Spanish, menus
and all. I checked KDE and it had my settings as Canadian English. So I
looked at the Spanish Rekonq settings and found it was Catalan. The
shortform for both is CA. I could not find anything that made sense because
I do not speak Catalan. So from the list of languages I saw something that
might be English but turned to be some unreadable script however I saw Elmer
Fudd in English in the list. I changed the settings and now saw Engwish in
the list. I changed to that and now all is fine.
So check the application settings in the receiving client. Also check
character encoding and font selection. I am not sure what they would be in
your case.
Ubuntu works differently from KDE in that it has no universal control panel
and locations settings have changed with Unity. I don't use a keyboard
changer so there may be some simpler explanation.
But it is nice that some KDE developer has a sense of humor and included
Elmer Fudd otherwise I might still be in some unreadable Asian script.
