[opensuse-m17n] Chinese Font under KDE

Hello, is it possible to define the font, which will be normally used for Chinese characters under KDE? I have installed several chinese fonts for traditional and simplified characters. The characters are already displayed under KDE, but the problem is, that they are very small and have always the same size. I think KDE uses some bitmap fonts which are only avaible in this small resolution and is not using truetype fonts which could be scaled. Bye Florian
