I have several programs (Notepad, Google PinYin, ...) which can display Chinese unicode without problem under Windows 8. Be it Simplified Chinese or Traditional Chinese.
However, when comes to my new Windows 8, I get the following problem
Note, change the "Language for non-unicode programs" won't help. As in old Windows 7, I still leave it as English too. Since Notepad and Google PinYin both support unicode, they can display both Simplified Chinese and Traditional Chinese very well.
For font setting, I change remove Hide fonts based on language settings. But, that won't help.
