XMLString::transcode added garbage characters

           Summary: XMLString::transcode added garbage characters
           Product: Xerces-C++
           Version: 1.6.0
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Utilities
        AssignedTo: xerces-c-dev@xml.apache.org
        ReportedBy: hogura@jp.ibm.com


I found the bug on Xerces 1.6.0, but I had not found on XML4C 2.4.3.
When XMLString transcode a text that includes entity reference: "&lt;", "&gt;" 
using XMLString::transcode() method, then the method add garbage characters to 
original characters.

Sample code is following:

#include <util/PlatformUtils.hpp>
#include <framework/MemBufInputSource.hpp>
#include <util/TranscodingException.hpp>
#include <dom/DOM_DOMException.hpp>
#include <parsers/DOMParser.hpp>
#include <dom/DOM.hpp>
#include <string.h>
#include <iostream>

// The text includes entity reference: "&lt;", "&gt;".
char* srcStr = "<text>&lt;aaaaa&gt;aaa</text>";

int main(int argc, char* argv[])
{
	XMLPlatformUtils::Initialize();
	DOMParser parser;
	parser.setDoValidation(false);
	MemBufInputSource* memBufIS = new MemBufInputSource((const XMLByte*)
srcStr, strlen(srcStr), "test");

	parser.parse(*memBufIS);

	DOM_Node node = parser.getDocument().getDocumentElement();
	DOM_Node child = node.getFirstChild();
	DOMString domStr = child.getNodeValue();

	// DOMString::transcode : success
	char* dch = domStr.transcode();
	std::cout << dch << std::endl;

	// XMLString::transcode : error!!!!!!!!!! added garbage characters
	char* ch = XMLString::transcode(domStr.rawBuffer());
	std::cout << ch << std::endl;

	XMLPlatformUtils::Terminate();
	return 0;
}

Output result:
<aaaaa>aaa
<aaaaa>aaa��������
