Yes, setting up a proper font, in particular, Arial Unicode MS, should solve the problem. I have no idea why you failed to do that, as you did not explain how you tried. This is really simple thing.
To check up what
character repertoire is supported by what form, use the application which is bundled with all versions of Visual Studio: "Character Map" (charmap.exe).
Also, instead of hard-coding UI for just Chinese, consider using globalization and localization instead:
