title: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in position 33: invalid continuation byte
body: <p>I've been having problems installing matplotlib toolkit for my python. 
  After giving the command <strong>pip install basemap-1.1.0-cp36-cp36m-win32.whl</strong>
  to my windows command promt, the install begins shortly and runs for a while, but after that, it stops and just gives me the following message:</p>
  
  <pre><code>Exception:

      return s.decode(sys.__stdout__.encoding)
  UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in position 33: invalid continuation byte
  
  During handling of the above exception, another exception occurred:

  <p>I tried to look for answer, but everything I could find had nothing to do with installing, but with code that was written by the user itself, so I got no clue how to apply that information to my case.</p>
