Java XMLReader not clearing multi-byte UTF-8 encod

问题:

I've got a really strange situation where my SAX ContentHandler is being handed bad Attributes by XMLReader. The document being parsed is UTF-8 with multi-byte characters inside XML attributes. What appears to happen is that these attributes are being accumulated each time my handler is called. So rather than being passed in succession, they get concatenated onto the previous node's value.

Here is an example which demonstrates this using public data (Wikipedia).

public class MyContentHandler extends org.xml.sax.helpers.DefaultHandler {

    public static void main(String[] args) {
        try {
            org.xml.sax.XMLReader reader = org.xml.sax.helpers.XMLReaderFactory.createXMLReader();
            reader.setContentHandler(new MyContentHandler());
            reader.parse("http://en.wikipedia.org/w/api.php?format=xml&action=query&list=allpages&apfilterredir=redirects&apdir=descending");

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    public void startElement(String uri, String localName, String qName, org.xml.sax.Attributes attributes) {
        if ("p".equals(qName)) {
            String title = attributes.getValue("title");
            System.out.println(title);
        }
    }
}

Update: This complete example produces (apologies to any Cantonese speakers for the vulgar output):
