asian language support in openoffice document

[Roger Searle]

Hi, does anyone have any experience with Asian language support in 
documents?  I have received a doc which apparently has Chinese 
characters in it (mixed in with English) but which displays various 
unicode characters in substitution.  I perhaps need to address 2 issues, 
in kubuntu and then in OpenOffice, but am looking for any advice anyone 
may have in getting this to work. 

I am told by other viewers (overseas) that they see the characters 
however they probably have the relevant fonts installed on their local 
machines and are no doubt running flavours of Windows and using Word.  
Any pointers would be appreciated.

Cheers,
Roger
