Hi,
the XMLParser.parseString() method raises an exception

UnicodeEncodeError: 'ascii' codec can't encode characters in

if the string to be parsed is a unicode strings and contains some
non-ascii
chars. The following snippet from a private unittest
(test_xmlparsers.py)
shows the error.
def test_xx(self):
xml = unicode('<?xml version="1.0" encoding="utf-8"?
><foo>üöä</foo>', 'iso-8859-15')
self._run_check(xml, ())
I am not sure if this behavior is intentional?! Is the XMLParser
supposed
to deal with unicode strings or will it only accept a standard
Python string? A workaround inside parseString() would to check for
unicode
and convert the string on-the-fly to a Python string with utf-8
encoding.
This is possibly a limitation of the underlying Expat parser...any
recommendation how to deal with this issue?
IMHO it should only accept strings, because in the value should be a
xml string and therefore always has to be encoded in 'utf-8' or in
the encoding specified in the processing instruction.
