The function of commands re Chinese input

[Stephen Liu]

Hi folks,

FreeBSD 5.2
OpenOffice 1.1.0

I have tried several days to add Chinese editing function to OOo 1.1 without a 
solution.  From searching I found following information advising that it can 
be solved with 3 commands

csh shlle
setenv LANG zh_CN.eucCN
setenv LC_CTYPE zh_CN.eucCN 

but without explanation.  Kindly assist me to understand what are those 
commands.

Furthermore I have installed 'xcin25' to my OS which are Chinese input device 
including fonts packages.  But I could not locate where those fonts have been 
installed.

Kindly advise.  TIA

B.R.
