Just a quick note: using java.io.Reader would not require people to
use Sun's character converters, unless the implementor chose to use
java.io.InputStreamReader or something similar.  You could always
subclass Reader to use your own character converters anyway.

That said, I'm happy to be persuaded to use SAXCharacterStream (or
SAXUTF16Stream) and SAXByteStream -- they'd make life much easier for
CORBA types.  The Java people will complain quite a bit that I'm not
using Reader and InputStream, but I can prepare a friendly canned
reply for them.


All the best,


David
