cocos-2d 跨平台GB2312转UTF8

android默认的字体是GB2312,在xcode中,转换成UFT-8

char* HelloWorld::G2U(const char* gb2312) 

int len = MultiByteToWideChar(CP_ACP, 0, gb2312, -1, NULL, 0); 
wchar_t* wstr = new wchar_t[len+1]; 
memset(wstr, 0, len+1); 
MultiByteToWideChar(CP_ACP, 0, gb2312, -1, wstr, len); 
len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL); 
char* str = new char[len+1]; 
memset(str, 0, len+1); 
WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL); 
if(wstr) delete[] wstr; 
return str; 
}
