Cannot install the package by pip due to some encoding error

When I try to install the package via pip command, it generates the following error message:

Collecting pygetwindow (from pyautogui)
Downloading https://files.pythonhosted.org/packages/f1/54/740939161eb3471e8f775ce9b0fcac0e54c36bf63501e51f2cd7158f587d/PyGetWindow-0.0.3.tar.gz
Complete output from command python setup.py egg_info:
Traceback (most recent call last):
File "", line 1, in
File "C:\Users\******\AppData\Local\Temp\pip-install-wflouosi\pygetwindow\setup.py", line 11, in
long_description = fh.read()
UnicodeDecodeError: 'gbk' codec can't decode byte 0xa2 in position 905: illegal multibyte sequence

So I tried to modify the setup.py and change the line 11:
Original:
`with open("README.md", "r") as fh:
long_description = fh.read()
`
New:
`with open("README.md", "r", encoding="utf-8") as fh:
long_description = fh.read()
`

It looks like this change can bypass the issue,
