Now I get it. Thanks. See my comments inline.

Free bonus tip: Buffer the output stream. In production environments this
can really make a difference in performance.

If you really want to concat your XML file this way, I'd use the
following:
encoding=3D\"UTF-8\"?>\n)

and...
new ByteArrayInputStream(xmlString.getBytes("UTF-8"))=
);
=2E...then you're problem should be solved, because the FNC_1 character is
then properly encoded in the XML. With UTF-8 you won't have any problems
with missing characters. Remember that Java uses Unicode internally with
Strings.
Personally, for this approach I would have generated SAX events by hand
instead of concatenating the XML as a String. That allows me to remove
the encoding and subsequent decoding (by the XML parser). Less buffering,
no encoding problems but may be a bit more complicated but only until
you've done that one time. I wrote an example for this:
http://xml.apache.org/fop/embedding.html#ExampleObj2XML
Obviously, this is a bit of overkill for this here, but you wouldn't
have had these problems. :-)

I hope this helps.
