Log:
Since SAX won't let us access the encoding used for a document, but rather converts to unicode, we now always write out XML in UTF-8 encoding.

issue41 testing

As i read, we can't handle this in SAX (SAX has no way to introspect encoding
from xml header), so we can consider require all .g* to be in UTF-8.

Note to self: investigate using (xml.sax.saxutils.XMLGenerator) instead of using
print commands to output our XML.

I am at a loss as to how we can properly do this using the SAX reader.  It
converts any XML it reads into Unicode, and recommends any output using the UTF-8. 

I've read this, which follows the same route: 

 * http://www.xml.com/pub/a/2002/11/13/py-xml.html

Designer loses custom xml encoding= attribute and defaults back to utf-8.
If you manually specify in your GFD file, for example:
    <?xml version="1.0" encoding="iso-1859-2"?>
then save it, the form will be written as:
    <?xml version="1.0"?>
This will affect our international customers.
