Xerces Serialize XML data and encoding

the next code works fine on Xerces 2.6 - helper function to convert bytes  to utf8 format.

void convertToUTF8(const XMLCh* buffer, CString &utf8_string)

{

XMLTranscoder* utf8Transcoder;

XMLTransService::Codes failReason;

utf8Transcoder = XMLPlatformUtils::fgTransService->makeNewTranscoderFor("UTF-8", failReason, 16*1024);

size_t len = XMLString::stringLen(buffer);

XMLByte* utf8 = new XMLByte[(len*MB_LEN_MAX)+1];

unsigned int eaten;

unsigned int utf8Len = utf8Transcoder->transcodeTo((buffer), len, utf8, len*MB_LEN_MAX, eaten, XMLTranscoder::UnRep_Throw);

utf8[utf8Len] = '\0';

utf8_string = (char*)utf8;

delete[] utf8;

delete utf8Transcoder;

}
