Yes, you are quite right that XML should take care of it.  And also
right that using Java Readers and Writers addresses the
well-formedness issue.  Generally, XML management is quite easy in
Java 6.  However, my experience has been that some browsers do not not
render some characters (or encodings?) perfectly and so I wondered
whether there are recommendations.
