There are some of the nice software such as TTplayer, Xunlei(Thunder) etc. are all written by Chinese and thus the interfaces of those software, of course, in Chinese language as well. Ever since the time for Windows XP, there are a lot of problem (mostly messy characters) when running those Unicode-based software. However, with Microsoft Applocale released, it is a very famous solution for executing Unicode software eg. Japanese and Chinese game, Chinese software etc. Although it is a good solution for Windows XP and above (for Vista and above, Applocale requires elevated command prompt to install), which obviously included Windows 7, but I have found another way of using Unicode-based-language software natively without installing anything.
