Convert hex string to Chinese chars

[Lorey]

Hi experts!

Is there a more decent way to convert below example hex strings to actual chinese chars other than code below?

	// sample hex string		
	std::string str = "\\0030\\31\\70ED\\83AB\\6279\\5FD2\\004c\\0045\\0046";
	const unsigned int MAX_LEN = 300;

	wchar_t* wStr = new wchar_t[(MAX_LEN)+1]; 
	memset(wStr,0x00,(MAX_LEN)+1);
	unsigned short wStrCtr = 0;
	for(unsigned int i = str.find("\\", 0); i != std::string::npos; i = str.find("\\", i))
	{
		unsigned int nextPos = str.find("\\", i+1);

		std::string st = str.substr(i+1,nextPos-(i+1));

		//validate the hex string
		if (4 != st.length() )
		{
			std::ostringstream os;
			os << std::setfill('0') << std::setw(4) << (st);
			st = os.str().c_str();
		}

		unsigned int val=0;
		sscanf (st.c_str(), "%x", &val);

        unsigned char highByte = static_cast<unsigned char>((val & 0xFF00) >> 8);
        unsigned char lowByte = static_cast<unsigned char>(val & 0xFF);

		wStr[wStrCtr++] = ((highByte & 0x00FF) << 8) | ( lowByte & 0x00FF);

		i++;
	}

	//need to do this else there will be garbage at the end
	wStr[wStrCtr] = 0;

	// Get the byte length of wStr
	int byteLen = WideCharToMultiByte (CP_OEMCP,0,wStr,-1,0,0,0,0);
	char *finalMessage = new char[byteLen+1];
	memset(finalMessage,0x00,byteLen+1);
	WideCharToMultiByte (CP_OEMCP, 0, wStr, -1, finalMessage, byteLen, 0, 0);
	finalMessage[byteLen] = 0;
	
	SetDlgItemText(IDC_EDIT1, finalMessage);			
	UpdateData(false);		

	delete [] wStr;
	delete [] finalMessage;

Check in the <locale> header:

There might be something you can use in there.

You can use

1) strtok to split the strings
2) strtol to convert them to numbers

Are you sure it is MBCS and not Unicode? If it is, then assign the values straight to a TCHAR (wchar_t).

If it is Unicode, it says
