autoencoding issue

[eboo]

Hi all,
This has probably been asked before, but I can't find any info on it.

I'm using Tomcat 3.2.3, and I tried serving chinese (bg, big5) using jsp
and whenever someone views my pages, their browser's (IE 5, Netscape 4.7) 
autodetect for character encoding won't work, and they have to manually
switch the language to see the words.

If one saves the file from the browser, auto-detect works fine.

Any idea how I can resolve this?

Thanks.
