This seems to be a bug in
org.apache.xml.serialize.Encodings: it's using some internal class from 
something from Sun, sun/io/CharToByteConverter. The trouble with code 
using suns internal classes is that it's broken by design. 
Unfortunately, the XML serialization in eXist doesn't have debugging 
information from the code, so I can't really tell you where to start 
looking to see if you can fix it, beside looking at the getEncodingInfo 
method in org.apache.xml.serialize.Encodings .

The class comes from Xerces, so I've CC:ed both the developers from 
Xerces and eXist on this issue.

cheers,
