需要将返回的UTF-8数据转换为string，char等都支持的ansi

void ConvertUTF8ToANSI(CString strUTF8,CString &strANSI) //

{

	int nLen = ::MultiByteToWideChar(CP_UTF8, MB_ERR_INVALID_CHARS, (LPCTSTR)strUTF8, -1, NULL, 0);

	//返回需要的unicode长度

	WCHAR *wszANSI = new WCHAR[nLen+1];

	memset(wszANSI, 0, nLen * 2 + 2);

	nLen = MultiByteToWideChar(CP_UTF8, 0, (LPCTSTR)strUTF8, -1, wszANSI, nLen);    //把utf8转成unicode

	nLen = WideCharToMultiByte(CP_ACP, 0, wszANSI, -1, NULL, 0, NULL, NULL);        //得到要的ansi长度

	char *szANSI=new char[nLen + 1];

	memset(szANSI, 0, nLen + 1);

	WideCharToMultiByte (CP_ACP, 0, wszANSI, -1, szANSI, nLen, NULL,NULL);          //把unicode转成ansi

	strANSI = szANSI;

	delete wszANSI;

	delete szANSI;

}

或者利用C++11

void ConvertUTF8ToANSI()

{

	auto LocUtf8 = std::locale(std::locale(""), new std::codecvt_utf8<wchar_t>);

	std::wifstream wfin("temp1.xml");

	std::wstring wstr, content;

	wfin.imbue(LocUtf8);

	while(getline(wfin, wstr))

	{

		content += wstr;

	}

	wfin.close();

	system("del temp1.xml");

	//std::wcout.imbue(std::locale(""));

	//std::wcout << content << std::endl;

	std::locale::global(std::locale("Chinese-simplified"));

	std::wofstream wfout("temp.xml");

	wfout << content;

	wfout.close();

}

寻得一个不用解码的API
