Thank you Dr. Fabian for your reply. I can now have Chinese websites displayed correctly in Konqueror, but I still have some other Chinese problems unresolved.
When your X11 session starts xcin should start automatically as well and you should see a small, blue window with title 'xcin 2.5.2.3'. Do you see this window?
I saw the window. At first I couldn't get it changed to have Chinese input method using Ctrl-Space, but after I specified zh_TW instead of zh_TW.Big5 in ./.xinitrc, xcin works now. I have upgraded to 2.5.2.3 today. However, I find that I cannot logout KDE properly everytime, probably because of xcin. On choosing "logout" the whole KDE freezes and I have to use Ctrl-alt-bksp to get out.
and changed the country settings in KDE to tw; zh_TW.Big5; Big5 charset. What I get is all garbage (looks like a Chinese webpage displayed using Western codepage),
I still get garbage in KDE menus and many KDE applications. But I can see Chinese correctly in Konqueror now. I don't know why, but if I use a font size too small, the garbage appears again. In the user account I am testing chinese I don't use anti-aliasing, because the installed fonts are not true type fonts and they don't appear in my primary account that has anti-aliasing enabled. Chinese characters in KDE applications still show up as ??? or rectangular squares or garbage. For example, in licq the Chinese nicknames are displayed as squares while kword displays the chinese words as ???. Switching to chinese fonts simply doesn't help. Although I still have some problems, at least this is a good beginning. Thank you very much again for your information. That's very useful. If other Chinese problems can as well be solved my SuSE experience would then be perfect.
