Clipboard transfer: Is there a way to transfer Chinese characters?

[liu yan]

Hi all:
I've used vnc for several years, currently i'm using RealVNC Free Edition 4.1.2.

The big issue I encountered is clipboard transfering with Chinese characters, 
it seems all chinese characters are stripped out when clipboard data transfered 
from/to the other side.

I've also tried UltraVNC or TightVNC, I got the same result. So, is it caused 
by vnc protocol? and, is there a way to transfer Chinese/Multi-Bytes characters 
between vnc client and server?
