GB2312和 UTF8的互相转换函数

本文主要是介绍GB2312和 UTF8的互相转换函数，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

//将GB2312转化为UTF8 string UpdateModule::GB2132ToUTF8(string strSrc) { string result; WCHAR *wstrSrc = NULL; char *szRes = NULL; int i; // GB2312转换成Unicode i = MultiByteToWideChar(CP_ACP, 0, strSrc.c_str(), -1, NULL, 0); wstrSrc = new WCHAR[i+1]; MultiByteToWideChar(CP_ACP, 0, strSrc.c_str(), -1, wstrSrc, i); // Unicode转换成UTF8 i = WideCharToMultiByte(CP_UTF8, 0, wstrSrc, -1, NULL, 0, NULL, NULL); szRes = new char[i+1]; WideCharToMultiByte(CP_UTF8, 0, wstrSrc, -1, szRes, i, NULL, NULL); result = string (szRes); if (wstrSrc != NULL) { delete []wstrSrc; wstrSrc = NULL; } if (szRes != NULL) { delete []szRes; szRes = NULL; } return result; }                                                                      GB2312和 UTF8的互相转换函数
