Don't do attachments on Usenet.

as they should. XML should be encoded in UTF-8 nearly always.

But SAX is a parser, so it doesn't output, it inputs. What are you telling us?

You used the default encoding in your Writer.

Your problem is writing the file, no? That has nothing to do with parsing.

If your problem is with reading the file, then the encoding in the XML declaration 
should suffice to guide the parser. But then why do you talk about methods that 
"output an encoding"?

However, according to 
http://xmlwriter.net/xml_guide/xml_declaration.shtml#Encoding
supported encodings only include UTF-8, UTF-16, ISO-10646-UCS-2, 
ISO-10646-UCS-4, ISO-8859-1 to ISO-8859-9, ISO-2022-JP, Shift_JIS, and EUC-JP, 
as you would have learned had you researched your question.

So it looks like you must not accept XML documents with such a non-standard 
encoding.

Show us the code, or at least an SSCCE of it.
