Viewing chinese characters with Mozilla

[jlr_0@yahoo.com (jlk)]

I'm using Mozilla 1.4-2 under a linux/Debian 2.4.21.

Sometimes I can browse web pages holding chinese characters without
any problem (like http://www.tigernt.com/cgi-bin/cedict.cgi) and
sometimes I cannot read them (like
http://ffii.org/archive/mails/cjk/2003/Jan/index.html).

Does anyone know what's wrong with my configuration?

Thanks for your help.
