I don't have Office installed, nor do I have multilingual support for XP as far as I know (which would explain why I complained about Guu's chess pieces custom title weeks ago).

I just checked ICQ -- it suports chinese text. This is what I did:

-open IE (gasp)
-right click on some non-link area
-choose encoding
-choose language
-insert Windows CD
-if it asks, replace the drive letter so windows knows where to copy the files from
-viola
