'utf-8' codec can't decode byte 0x80 in position 0 - django

Question

Ok when i'm in django I can run the website by the following command.
sudo python manage.py runserver
But when I try and use the greed arrow for running the project is gives me like a dozen errors.
This happens straight away when i set up the project and was hoping if anyone could help.

I was getting a similar error for a different issue, but it turned out that it was a problem with the way PyCharm handled Unicode/UTF-8 with Python 3. I ended up doing the following to get the error to go away.
Add following line in the file "pycharm.exe.vmoptions":
-Dfile.encoding=UTF-8
Source:
Why unicode string is not shown on PyCharm's console?
Hope this helps!
