Errors encountered installing git-deps under Windows

I'm not able to run "pip install git-deps" under Windows 10.

` error in setup command: Error parsing C:\Users\johndog\AppData\Local\Temp\2\pip-install-_m6ma4lh\git-deps\setup.cfg: UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 910: character maps to
`
I ran pip with --no-clean and looked at the setup.cfg, but I didn't see any problems in it (or even a byte 0x9d), so it must be somewhere else than implied by the error message.

```

```

Start with setup.cfg and the setup.py packaging path shown in the error, then reproduce `pip install git-deps` on Windows 10 using the reported Python 3.7 environment. Done means the package installation completes without the UnicodeDecodeError during metadata generation.
