You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Google is giving you bad advice. Or am I approaching the issue from the wrong side.

The C compiler for Python 2 is installed. If you need additional information - ready to answer any question.
UPD: I'll clarify the question - I know how to deal with encoding in my scripts. Here, problems got out when installing the FreeSWITCH-ESL-Python library on Windows Server 2016 x64 (Win10 / Win7 - similar problems). Editing the library itself seems wrong to me. Maybe there are other solutions?
UPD1: On Python 3, the error log is like this.

Upgrading pip to 8.1.2 will not change the situation.
