This looks rather broken. Are you sure this is what your code looks like,
or did just you type this into your email while trying to strip down your
actual code into a simpler example?

Note that lxml can parse from Unicode, so once you have decoded your data,
you can just pass it into the parser as is, e.g.
mytree = etree.fromstring(content.decode('windows-1252'))
This is not something I'd encourage since it requires a bit of back and
forth encoding internally and is rather memory inefficient, but if your
decoding is non-trivial, this might still be a viable approach.

Same thing as above: I don't see how this error message matches the code
you show here. The exception you get might be a Python 2.x problem in the
first place.
