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?
