Hi Matthew
Sorry for just chiming in here out of the blue. I don't really know
anything on the code you are discussing, but I have some experience with
python.

My guess is that the function part.get_content_charset is requesting the
encoding used for a message, providing 'ascii' as a backup if not found.
It is getting 'latin-1', which is hence tried for encoding output.

Here is an interactive python session to reproduce:
>>> u = u'\u201c'
>>> u
u'\u201c'
>>> type(u)
<type 'unicode'> # (un-encoded)
>>> u.encode('utf-8')
'\xe2\x80\x9c' # utf-8 for encoding work fine
>>> print u.encode('utf-8')
“
>>> print u.encode('latin-1')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'latin-1' codec can't encode character u'\u201c' in position 0: ordinal not in range(256)
The character is not encodable with latin-1. So one should check that
the function getting the encoding is doing a proper job and if so blame
the message information.
Just my 2 cents
Best regards
