Simplified Chinese pages (uses default font and doesn't print) -- Windows

[MATTHEWS,HEATHER (HP-Vancouver,ex1)]

Hi,
        When opening a Simplified Chinese page (charset = GB2312) in Mozilla
I notice that a system default font is used rather than one specified in a
style sheet.  In addition, when I try to print any GB2312 pages, all
characters are question marks.  Is this bug already known?  I have searched
in bugzilla and can't seem to find anything related.  To reproduce browse to
http://cn.yahoo.com/ on a Simplified Chinese Windows system.  You will
notice the font is a default font and is applied to all characters.  If you
browse to this same page on an English Windows OS (that has the proper
character set installed), you will notice the page is displayed correctly.
In addition, the page prints "?" on a chs system but prints the correct
characters on an English system.  This defect has manifested itself as quite
a big deal for our company.  Can anyone help me?
