Display Japanese characters

I’m developing a mini game which display a list of japanese strings using CCLabelTTF But it just display like “???”. I have already searched on goolge but still do not know why. I’m using Visual Studio 2013, cocos2d-x 2.2.4 Can anyone give me a solution? Thank you for your help.

Convert your source code to UTF8 format. As you can see, cocos2d-x test case is rendering Japanese characters properly.

Windows system in China use GBK code instead of UTF8, as the result Visual Studio is not using UTF8 by default in China, which leads to the similar error. I guess it’s similar in Japan.
