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

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

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?
Traditionally, you parse an 8bit string, figure out its encoding (e.g.
from <?xml encoding="utf-8"?> and return some representation of that XML
with unicode data. That's why it's actually quite ok for XML parsers to
only accept string data.
With ZPTs it's a bit different: When editing ZPTs TTW for example, we
like to store its source in unicode. So it makes sense for us to be able
to parse unicode input as XML.
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?
Fixed it in 3.3 and trunk. If you had given me a bit more time, this
could even have been in 2.10.2b :). Oh well, I guess that's what 2.10.2
will be for ;)
