GBK转utf8如下：

string GBKToUTF8(const std::string& strGBK)  {      string strOutUTF8 = "";      WCHAR * str1;      int n = MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, NULL, 0);      str1 = new WCHAR[n];      MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, str1, n);      n = WideCharToMultiByte(CP_UTF8, 0, str1, -1, NULL, 0, NULL, NULL);      char * str2 = new char[n];      WideCharToMultiByte(CP_UTF8, 0, str1, -1, str2, n, NULL, NULL);      strOutUTF8 = str2;      delete[]str1;      str1 = NULL;      delete[]str2;      str2 = NULL;      return strOutUTF8;  }

utf8转GBK如下：

string UTF8ToGBK(const std::string& strUTF8)  {      int len = MultiByteToWideChar(CP_UTF8, 0, strUTF8.c_str(), -1, NULL, 0);      unsigned short * wszGBK = new unsigned short[len + 1];      memset(wszGBK, 0, len * 2 + 2);      MultiByteToWideChar(CP_UTF8, 0, (LPCTSTR)strUTF8.c_str(), -1, wszGBK, len);      len = WideCharToMultiByte(CP_ACP, 0, wszGBK, -1, NULL, 0, NULL, NULL);      char *szGBK = new char[len + 1];      memset(szGBK, 0, len + 1);      WideCharToMultiByte(CP_ACP,0, wszGBK, -1, szGBK, len, NULL, NULL);      //strUTF8 = szGBK;      std::string strTemp(szGBK);      delete[]szGBK;      delete[]wszGBK;      return strTemp;  }

C++头文件包含文件：

#include <iostream>  #include <string>  #include <fstream>  #include <windows.h>
