the real reason to make it work is that, the function ANSI2UTF8 convert ANSI->UNICODE->UTF8 that makes it possible to mix any ASCII and wchars, and it works prefectly well. 

You can just have a sample test to see the effet. For example: set PPSSPP_GIT_VERSION as "version 版本", and complie the code. Now you can observe that the title is correctly displayed. But the old code can not display the chinese caracter at all.
