XercesC setting output to UTF-8

Question

I'm using XercesC Lib to create a serialization of my data. How can I set it to UTF-8? It is always generated with UTF-16 and I can't find a way to change that.

xercesc::DOMImplementation *gRegistry = xercesc::DOMImplementationRegistry::getDOMImplementation(X("Core"));
xercesc::DOMDocument *doc = gRegistry->createDocument(
        0,                      // root element namespace URI.
        X(oDocumentName.c_str()),       // root element name
        0);                 // document type object (DTD).
doc->setXmlStandalone(true);
... prepare the document ...
serializer = ((xercesc::DOMImplementationLS *)gRegistry)->createLSSerializer();
serializer->setNewLine(xercesc::XMLString::transcode("\n"));

XMLCh *xmlresult = serializer->writeToString(doc);
char *temp = xercesc::XMLString::transcode(xmlresult);
std::string result(temp);

xercesc::XMLString::release(&temp);
xercesc::XMLString::release(&xmlresult);
doc->release();
serializer->release();
getStream() << result.c_str();

When I deserialize with JAXB on the Java side, I always get a content is not allowed in prolog and so far this is the only difference I can see in the XML. When I try to locally deserialze in JAXB it works. When I take my XercesC XML I get this error. When I try to format it in Notepad++ with the XML plugin it also says that there is an error, but doesn't tell me any details.

Check the usage of DOMLSOutput, that should give you exactly what you want. I.e. you create a DOMLSOutput object to which you write (instead of using DOMLSSerializer::writeToString).
