I tried naively running 2to3 over the SpamBayes source code on my Mac
and got this traceback:

Traceback (most recent call last):
File "/Users/skip/local/lib/python3.2/lib2to3/pgen2/tokenize.py", line 281, in find_cookie
codec = lookup(encoding)
LookupError: unknown encoding: mbcs

SpamBayes does have several files which contain the "mbcs" coding
cookie:

./windows/py2exe/gen_py/addin-designer.py
./windows/py2exe/gen_py/office-9.py
./windows/py2exe/gen_py/outlook-9.py

After a little hunting I came across the docs for the codecs module,
which for "mbcs" states:

Windows only: Encode operand according to the ANSI codepage (CP_ACP)

Is there something I can use to replace the mbcs coding cookies which
will allow 2to3 to process these Windows-specific files?

Thanks,

Using mbcs as the source encoding declaration is evil (and stupid too).
mbcs means "whatever encoding is currently configured in Windows", it is
not a specific encoding.
You have to guess which encoding those files are in. windows-1252 (almost
the same as latin-1) is the one used in "Western Europe", which covers an
area much broader than its name.

Good luck,
