How to put special chars into XmlPackages. See this page for char encoding:
http://htmlhelp.com/reference/charset/
For example, you can't use it is not a valid XML escape character you need to use & # 1 6 0 ; and your output encoding should be iso-8859-1.
To output a copyright symbol, in HTML it is © but in XmlPackage it would be & # 1 6 9 ; (no spaces in between those characters. I had to put spaces so the forums don't output it as ©
There are only five character entities in XML: &, <, >:; " and '
All other escape sequences are hex or decimal character values of the encoding that is set for output.
etc.
