Getting 'NoneType' object has no attribute 'encoding' when running with pythonw

Getting 'NoneType' object has no attribute 'encoding' when running with pythonw (non-CLI)
Believe due to "pythonw" has NO standard streams sys.stdin, sys.stdout and sys.stderr available
No problem when running with "python" (with CLI)

Hi! I've fixed that issue with my pull request, setting the encoding to UTF-8. The reason you had the bug was because it sets the encoding to whatever encoding you're using in your command line. If you python without the command line, like a .pyw file, than sys.stdout doesn't exist, since it's basically the command line. In short, just change sys.stdout.encoding to python's default, "UTF-8".

Sorry, correction to the above statement: use cp437 encoding instead of utf.
