SHORT SUMMARY:
If XML output is generated using a TransformerHandler created by a
SAXTransformerFactory, Unicode supplementary characters are output
incorrectly.
Instead of a single numeric character entity for the supplementary character,
two entities are generated, representing the low and high surrogates.
This is a regression in 1.7.0_04 - there are no problems in earlier releases
of 1.7 or in the latest release of 1.6.
INDICATORS:
None
COUNTER INDICATORS:
None
TRIGGERS:
Here is a test to illustrate the problem:

import javax.xml.transform.sax.SAXTransformerFactory;
import javax.xml.transform.sax.TransformerHandler;
import javax.xml.transform.stream.StreamResult;

import org.xml.sax.helpers.AttributesImpl;

public class ucout {

  private static final char [] CHARS =
  String.valueOf(Character.toChars(0x12000)).toCharArray();

  public static void main(String[] args) throws Exception {
    TransformerHandler th = ((SAXTransformerFactory)
    SAXTransformerFactory.newInstance()).newTransformerHandler();
    
    th.setResult(new StreamResult(System.out));    
    th.startDocument();
    th.startElement("", "", "c",  new AttributesImpl());
    th.characters(CHARS, 0, CHARS.length);
    th.endElement("", "", "c");
    th.endDocument();
    System.out.println();
  }

If the test is run with 1.7.0_04 the (incorrect) output is:
<?xml version="1.0" encoding="UTF-8"?><c>��</c>

If run with 1.6 or 1.7.0_03, the (correct) output is:
<?xml version="1.0" encoding="UTF-8"?><c>𒀀</c>

 KNOWN WORKAROUND:
 No
 PRESENT SINCE:
 N/A
 HOW TO VERIFY:
 Run attached test case
 NOTES FOR SE:
 None
 REGRESSION:
