Cannot type accented capital letters in kde-konsole

view story

http://unix.stackexchange.com – If i try to type a capital letter with accent (e.g. Ř) in kde-konsole, I get the following result: ˇR - the letter and the accent as two characters. The normal behaviour is that after pressing ˇ character, it is not output immediately but another character is expected. In the konsole tho, the character is output immediately. In other applications, it works fine. I am using gnome and in it the kde-console application. Any directions how to solve this? (HowTos)
