XML 1.0 does not allow that character.
I think XML 1.1 allows it if escaped with a character reference
  (e.g. & # x 1 D;, without the spaces). However Microsoft does not have 
parsers that support XML 1.1.

With the Microsoft .NET framework 2.0 or later you should also be able 
to use version="1.0", escape the character as shown above and then parse 
it with an XmlReader with XmlReaderSettings where CheckCharacters is set 
to false:

             XmlReaderSettings xrs = new XmlReaderSettings();
             xrs.CheckCharacters = false;

             using (XmlReader xr = XmlReader.Create("input.xml", xrs))
             {
                ...
             }


The proper way with XML 1.0 however would be to base64 encode such 
characters, that way you would be able to pass the file around as XML 
1.0 and any XML parser can deal with it.
