I still believe it to be a Java input issue, although this could get tricky because you are not creating your own InputSource and/or InputStream, you are relying on the implementation of the parse(String) method to do it properly.
My inclination is that the parse(String) method is creating an InputSource
object with some default encoding that is not completely compatible with the
input you're giving it (i.e. you have characters outside the range of the
default character encoding) which gives you the '?' characters.
If you know your encoding (Unicode, UTF-8, ISO-8859-1, etc.) you can try
creating the InputSource yourself and setting its encoding by using the
following methods:
InputSource urlSource = new InputSource(url.toString());
urlSource.setEncoding("UTF-8");
parser.parse(urlSource);
I believe ISO-8859-1 is the encoding you're looking for where   =  
= non-breaking space
(http://www.htmlhelp.com/reference/charset/iso160-191.html).
Good luck!

Yes - no joy.

I use:
LMLDocumentHandler myDocumentHandler = new
LMLDocumentHandler(this,url);
DocumentHandler documentHandler = myDocumentHandler;
parser.setDocumentHandler(documentHandler);
LMLErrorHandler myErrorHandler = new LMLErrorHandler();
....
try {
parser.parse(url.toString());
,..... ETC
so theres no issues with input. Admittedly this is the old API but as I
say - everything worked OK under jserv / jdk 1.1
Could it be something to do with the character sets that the JVM (jre)
understands? And if so how do I tell it about other char sets.

|Dear Esteemed collegues,

|I have tried other parsers, eg, aelfred, and get the same effect. Now I

|
|I'm sure this is a very simple problem .... but what is the solution?
