ANSI与UTF-8编码互相转换

std::string EncodeConvert(std::string sInfo, int sourceEncode, int targetEncode)
{
	// convert unicode
	const char* buf = sInfo.c_str();
	int len = MultiByteToWideChar(sourceEncode, 0, buf, -1, NULL, 0);
	std::vector<wchar_t> unicode(len);
	MultiByteToWideChar(sourceEncode, 0, buf, -1, &unicode[0], len);
	wstring wstr(&unicode[0]);

	// convert MultiByte
	const wchar_t *wbuf =wstr.c_str();
	len = WideCharToMultiByte(targetEncode, 0, wbuf, -1, NULL, 0, NULL, NULL);
	std::vector<char> multi(len);
	WideCharToMultiByte(targetEncode, 0, wbuf, -1, &multi[0], len, NULL, NULL);
	string sMulti(&multi[0]);
	return sMulti;
}

ANSI->UTF8

EncodeConvert(sText, CP_ACP, CP_UTF8);

UTF8->ANSI

EncodeConvert(sText, CP_UTF8, CP_ACP);

CString,std::string,char*,const char*互相转换

CString cstr;

std::string stdstr;

char* pChar;

const char* pcChar;

CString->std::string

stdstr = (LPSTR)(LPCTSTR)cstr;

stdstr = cstr.GetBuffer(cstr.GetLength());

CString->char*

pChar = (LPSTR)(LPCTSTR)cstr;

CString->const char*

pcChar = (LPCTSTR)cstr;

std::string->CString

cstr = stdstr.c_str();
