Installing from source gives UnicodeDecodeError

[AbdealiLoKo]

When I install rsa with source, it fails with an ascii codec error.
It works if I install it with the wheel.

Environment Versions

1. OS Type CentOS 7
2. Python version: Python 3.6.6
3. pip version: pip 8.1.2 from /usr/lib/python3.6/site-packages (python 3.6)

Steps to replicate

$ docker run -it --rm centos:7 bash
# yum install -y epel-release
...
# yum install -y python36-pip
...
# pip3.6 install --no-binary :all: rsa

You are using pip version 8.1.2, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Seems like there's something wrong with the readme?
NixOS/nixpkgs#53116

Please test with the latest revision of the master branch, it should be fixed now. If you can confirm it's fixed, I can release it.

I can confirm that the problem is fixed on master for me at least.

Thanks for checking. I'm preparing version 4.1 for release soon.
