What's your 'Language for non-Unicode programs' set to? If you don't set it to 'Chinese (Simplified, China)', some programs will display broken characters. See this page for more information.
Thank you Xin and is very helpful information indeed !!!!
Your hints now lead me to start installing a separate USB Opera with Simplify Chinese as I am not wanting to touch the core Unicode in the Window system.
Thank you very much once again.
