Java.io.UnsupportedEncodingException

Question

Hello.
I am trying to parse an XML file into its DOM representation. The XML files starts with this line:
<?xml version="1.0" encoding="X-User-Defined"?>My code for parsing the XML is this:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
builder = factory.newDocumentBuilder();
Document doc = builder.parse(file);When run, I get this:
java.io.UnsupportedEncodingException: X-User-DefinedSo the problem is with the encoding of the XML file as specified. I'd like to know if there is a way to make the parser simply ignore the encoding attribute of the XML header. Or alternatively, treat it as an encoding that is supported.
Thanks.

Thank you. That worked.
I implemented a custom CharsetProvider and installed it per the instructions in the javadoc. I'll provide the implementation for future reference:
import java.nio.charset.Charset;
import java.nio.charset.spi.CharsetProvider;
import java.util.Iterator;
public class UserDefinedCharsetProvider extends CharsetProvider {
     public Iterator<Charset> charsets() {
          return null;
     public Charset charsetForName(String charsetName) {
          return Charset.forName("UTF-8");
}
