each time I run fuck in my powershell prompt, I get warned about mismatched stdin and stdout encodings:

c:\python34\lib\site-packages\win_unicode_console__init__.py:27: RuntimeWarning: sys.stdin.encoding == 'utf-8', whereas sys.stdout.encoding == 'cp1252', readline hook consumer may assume they are the same
readline_hook.enable(use_pyreadline=use_pyreadline)

I saw issue #486, but this issue is slightly different (the encoding isn't 'None').
