[jdom-interest] XMLOutputter problems with Unicode

[Mad Einstein]

I tryied to do this like that:

    Element root = new Element("indexes");
    Document doc = new Document(root);   //sample JDom Document

    FileWriter fw = new FileWriter("test.xml",false);
    new XMLOutputter(" ", true, "UTF-8").output(doc,fw);

And the result was as I said one byte 93hex insead of  \u8220

Should I use different writer? Do you know any writers that will give me
proper Unicode output?

Thanks,

Mad Einstein
