=====================
The filesystem encoding can be specified by setting the
:envvar:`PYTHONFSENCODING` environment variable before running the interpreter.
The value is an encoding name, e.g. ``iso-8859-1``. This variable is not
available (ignored) on Windows and Mac OS X: the filesystem encoding is pinned
to ``'mbcs'`` on Windows and ``'utf-8'`` on Mac OS X.
The :mod:`os` module has two new functions: :func:`~os.fsencode` and
:func:`~os.fsdecode`.
