WINDOWS下的ANSI字符串和UTF8字符串之间的相互转换

//CP_ACP=ANSI,CP_UTF8=utf-8CString CXXXApp::UTF8Convert(CString &str,int sourceCodepage,int targetCodepage){int len=str.GetLength(); int unicodeLen=MultiByteToWideChar(sourceCodepage,0,str,-1,NULL,0); wchar_t * pUnicode; pUnicode=new wchar_t[unicodeLen+1]; memset(pUnicode,0,(unicodeLen+1)*sizeof(wchar_t)); MultiByteToWideChar(sourceCodepage,0,str,-1,(LPWSTR)pUnicode,unicodeLen); BYTE * pTargetData; int targetLen=WideCharToMultiByte(targetCodepage,0,(LPWSTR)pUnicode,-1,NULL,0,NULL,NULL); pTargetData=new BYTE[targetLen+1]; memset(pTargetData,0,targetLen+1); WideCharToMultiByte(targetCodepage,0,(LPWSTR)pUnicode,-1,(char *)pTargetData,targetLen,NULL,NULL); CString rt; rt.Format("%s",pTargetData); delete pUnicode; delete pTargetData; return rt; }这段代码的出处忘记是哪了。修改了一下，可以使用
