CJK characters in xml element name

Question

Hi People,
I have a question as it looks like I am doing something wrong, but I do not know what.
I am trying to use CJK characters in the element name of an xml document and the element names are encoded/parsed using the default encoding and not the encoding specified at the xml document.
This is the specific code
     ByteArrayOutputStream baos = new ByteArrayOutputStream();
     Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
     document.appendChild(document.createElement("\ub3c4\uba54\uc778"));
     TransformerFactory tFactory = TransformerFactory.newInstance();
        Transformer transformer = tFactory.newTransformer();
        transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
        transformer.transform(new DOMSource(document), new StreamResult(baos));
        System.out.println(new String(baos.toByteArray(), "UTF-8"));
        System.out.println(new String(baos.toByteArray()));(you have to run this on a system that does not have UTF-8 as the default locale :-)
The result of this is
<?xml version="1.0" encoding="UTF-8" standalone="no"?><???/>
<?xml version="1.0" encoding="UTF-8" standalone="no"?><&#46020;&#47700;&#51064;/>
So the encoding of the element name is not UTF-8 but the default encoding.
Just in case someone ask
$ java -version
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13-120)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_05-b13-52, mixed mode)
Thanks,

Hi Alpha.23,
well I'm not sure, and maybe I'm totally wrong, but here is what I think about your problem.
As there is no error while running the code, there should be no XML problem (so the characters you are using are XML compatible for tag names).
I think the problem is the ability of any computer to display such chars. The questionmark often indicates that there is a char which cannot display correctly. This depends partitially on the font your are using.
If I try to display the chars with simple System.out.println("\ub3c4\uba54\uc778"); I get those question marks too. So I guess the console of my IDE (eclipse) can't display these Korean symbols. But I haven't installed the specific language-support for any of the Asian languages (so I don't know what happend when they are installed, though I guess that doesn't solve the problem...).
So my tip is first to look for a way to print these char in general (on the console, into a file, maybe try to create a word document because a unicode font -i.e. Arial Unicode- is able to print these - try ALT+47700 or ALT+46020).
