The description of Unix behavior for sys.getfilesystemencoding() listed


should probably change for Python 3.3. The behavior on Unix is the only
affected portion. According to the latest source at revision 293180d199f2
of the main hg repository, it is now a fatal error if the system call to
nl_langinfo(CODESET) fails to return a valid result, so Python does not
fall back to 'utf-8' encoding anymore. Instead, it aborts. In that light,
the bullet for Unix could now read:

   - On Unix, the encoding is the user’s preference according to the result
   of nl_langinfo(CODESET).

An applicable change note to replace the version 3.2 note would follow,

Changed in version 3.3: On Unix, it is now a fatal error if
nl_langinfo(CODESET) fails to return a valid result during interpreter
The relevant source commits are revision e2ba1249a2f5 and 7ce685cda0ae if
further verification is required.

Hope this helps.
