On the Stre@m

I found myself in the position to work with SAX and to construct some data structure based on a xml. In the xml there were charactere references along with other special characters like 鮠I needed to know when I got each of them so to construct the data structure correctly. Normally SAX is reporting both in the same way using characters() method from DefaultHandler. I posted this request of mine on bugzilla and Neil Graham was kind enough to tel me about this undocumented feature that SAX has:
http://apache.org/xml/features/scanner/notify-char-refs
Setting this on true will make SAX to report character references the same way as entities. But here is the code:

SAXParser xr = new SAXParser();
try {
  xr.setFeature("http://apache.org/xml/features/scanner/notify-char-refs", true);
} catch (Exception e) {
  System.out.println("Feature not supported");
}
