Calling `config_parser.read` with `'test'` is equivalent to:    config_parser.read(['test'])while calling `config_parser.read` with `b'test'` is treated as:    config_parser.read([116, 101, 115, 116])which means python will try to open the file descriptors 101, 115 and 116.I don't know if byte path should be supported, but this is probably not the expected behavior.The method code:https://github.com/python/cpython/blob/master/Lib/configparser.py#L678-L702

Good catch. Supporting bytes passed as a path is a reasonable request since the builtin `open()` supports this, too. Go ahead and create a pull request! We only need to modify line 690 to also list `bytes`.

This is related to the issue I'd brought up previously here so closing this would also close that issue:http://bugs.python.org/issue29627I did originally attempt to add support for bytes in PR where I added support for Path-like objects:https://github.com/python/cpython/pull/242 but I was asked to take it back out.

Thanks! I went ahead and mergedPR 3420 since Łukasz (the configparser maintainer) has accepted the idea.
