Debian default font for Chinese display is not complete

Hi guys!

I am currently using Debian in English but also need to display (and 
type eventually) Chinese. I followed some Internet resource to do that 
and it works almost well. The default font used by the system to do that 
is missing some Chinese characters. From all my KDE font settings it 
says it is Bitstream Vera, though after checking with Font viewer 
Bitsream Vera seems to have no Chinese character at all.

So I have in fact a few font related questions:
- how do I find out which font is really being used?
- How do you guys handle the problem?

- How in open office when opening documents written on wndows do you get 
the right font selection to display all the Chinese characters without 
having to do a Select all - replace?

Thanks.
