Why don't you just convert the string to unicode bofore feeding it to
parser.
That way you don't have to even declare the encoding in the file.
Correct encoding have to be set in sitecustomize.py in order to make
the example below work. See the Python FAQ at
http://www.python.org/cgi-bin/faqw.py?req=show&file=faq04.102.htp

>>> from xml.dom import minidom
>>> non_ascii = """<tag foo="Ä">ÄÖÅ</tag>"""
>>> print minidom.parseString(non_ascii.encode("UTF-8")).toxml()
<?xml version="1.0" ?>
<tag foo="Ä">ÄÖÅ</tag>
>>> print minidom.parseString(non_ascii)
Traceback (most recent call last):
