前一段时间，
使用COcos2dx 2.0,在使用中文转码的时候，老是加载出问题。

，原因是在引用第三方库的时候，只写了头文件，#include "platform\third_party\win32\iconv\iconv.h" 只要在头文件附近加入 #pragma comment(lib,"libiconv.lib") 即： #if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32) #include "platform\third_party\win32\iconv\iconv.h" #pragma comment(lib,"libiconv.lib") #endif 可解决中文问题，下面附带函数： int
HelloWorld::GBKToUTF8(std:
:string &gbkStr,
const char* toCode,
const char* formCod
E) { iconv_t iconvH; iconvH = iconv_open(formCode,toCod
E); if(iconvH == 0)
{ return -1; }
const char* strChar = gbkStr.c_str(
); const char** pin = &strChar; size_t strLength = gbkStr.length(
); char* outbuf = (char*)malloc(strLength*4
); char* pBuff = outbuf; memset(outbuf,strLength*4
); size_t outLength = strLength*4; if(-1 == iconv(iconvH,pin,&strLength,&outbuf,&outLength))
{ iconv_close(iconvH
); return -1; } gbkStr = pBuff; iconv_close(iconvH
); return 0; } //----------------------------------------------------- std:
