exception: invalid byte 1 of 1-byte UTF-8 sequence (0xb3)

[Frank Zhou <fc...@yahoo.com>]

Hi All,

I was trying to parse an XML file using xerces-J
latest version and got the invalidByte exception,
the problem has to do with a character "superscript 3"
with unicode 0xb3. I thought this is a legal XML
character according to the XML specification, and I
can load the xml document fine with Windows Explorer.
Any clue why I got this exception? 

Thanks much in advance.

Frank

You are probably seeing this exception because your
document does not specify the true encoding of the file.
Since Xerces defaults to UTF-8, it produces an error when
it sees a character from the true encoding and tries to
handle it as UTF-8.

Add an XML declaration at the top of the file that
specifies the real encoding. For example:

   <?xml version='1.0' encoding='ISO-8859-1'?>
