    This is a potentially annoying incompatibility between platforms.
    Under Linux:

    >>> import os
>>> print(os.device_encoding(1000))
None

    And under Windows:

    >>> print(os.device_encoding(1000))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: [Errno 9] Bad file descriptor

    This may be related to the following lines in posixmodule.c:

    if (!_PyVerify_fd(fd))
    return posix_error();

    Right, None is clearly the right result. Fixed in revision 70581
