It was OK as version 2003-4-15. but failed at 2003-4-18.
Knoppix was installed in hard disk with kde-i18n-zhtwbig4, kde-i18n-zhcngb2312, and used windows fonts (simsun), changed locale as China.
in KDE select smooth fonts. It smoothed the English fonts but failed to smooth Chinese (simsun). There must some changes from 2003-4-15 to 2003-4-18 to make it failed.
