title: UnicodeDecodeError when calling AWS CLI
body: <p>I just installed the AWS CLI following this installation guide for Windows:
  <a href="http://docs.aws.amazon.com/cli/latest/userguide/installing.html#install-msi-on-windows" rel="nofollow">http://docs.aws.amazon.com/cli/latest/userguide/installing.html#install-msi-on-windows</a></p>
  
  <p>However, when I execute <code>aws --version</code> in my cli the following error is thrown:</p>
  
  <pre><code>C:\Users\René Winkler&gt;aws --version
  Traceback (most recent call last):

  <p>What could be the cause of this problem?</p>
