XMLCh and std::wstrng (UCS-4) on Solaris

[Max Winther <ma...@wanadoo.dk>]

Hi

I am doing a project with xerces-c on a Sun Solaris UNIX - platform using the std::wstring, which is UCS-4 encoded. I have read a lot and searched around the net a lot. Can somebody please tell my an easier way to convert my std::wstring's into XMLCh than enlarging the XStr, taken directly form the sample CreateDomDucemnt, with the following constructor:

	XStr(const std::wstring& toTransCOde)
	{
		// construct a transcoder in UCS-4, do it static to reuse the transcoder
		XMLTransService::Codes resCode(XMLTransService::Ok);
		static XMLTranscoder* aUCS4Transcoder =  XMLPlatformUtils::fgTransService->makeNewTranscoderFor("ucs4", 
		                                                                                                resCode, 																								
																										4*1024);
		if (resCode != XMLTransService::Ok || aUCS4Transcoder == null)
		{
			//TODO handle error and return
		}

		unsigned int charsEaten;
		unsigned int srcCount = toTransCode.size();
		unsigned int maxChars = toTransCode.size();
		char[] charSizes[toTransCode.size()];

		//Construct a stack XMLCh, did not find a way to construct a heap XMLCh like XMLString::transcode(const char*)
		XMLCh localXMLCh[toTransCode.size() + 1];

		aUCS4Transcoder->transcodeFrom((XMLByte)toTransCode.c_str(), 
			                           srcCount,
									   &localXMLCh, 
									   maxChars, 
									   &charsEaten, 
									   &charSizes);

		//TODO Handle Errors: using charsEaten

		//Move the local stack XMLCh into the heap
		fUnicodeForm = XMLString::replicate(localfUnicodeForm);
	}
