The goal is to have UTF-8 file names, especially for MP3 files :). I added utf8 segment to the list of languages in knoppix-autoconfig with LANG=en_US.UTF-8 and CHARSET=UTF-8, but results are mixed: Konqueror displays file names correctly, but konsole doesn't, while xterm do. Is it possible to make konsole display proper characters instead of squares (changing the font does not seem to help), or should I switch to xterm? KDE taskbar also doesn't display UTF-8 characters at all, can it be fixed?

XMMS started to display proper characters in songs list and main window after specifying the good font group, but without selecting the font grouping option (first on on a Fonts page) since it brakes everything.
