fc1 can't display Chinese file name in x window ( RH9 could )

[Barry Yu]

I started the X window and selected the language in Chinese, I mounted 
my data file by ;

mount -o iocharset=cp950    /dev/dhl5   /mnt/ms

When I use ls to see my file in Chinese, it displayed something like 
"?????{????.doc"

Exact same procedure and commands I used in RH9, I could see the same 
file in Chinese characters perfectly.

Need help and thanks.
