title: UnicodeDecodeError: 'ascii' codec can't decode byte 0xcb in position 0: ordinal not in range(128) when using tastypie
body: <p>I am testing tastypie 1.9 with Django 1.4 to create a basic REST API for my website. I am following the initial steps in documentation, where I got stuck.</p>
  
  <p>I am running Django globally, and not using virtualenv for this specific implementation. It says in the browser <code>A server error occurred.  Please contact the administrator.</code>. I am running this in django server only.</p>
  
  <p>This is the error message that is coming in terminal when I try to access <code>http://127.0.0.1:8000/api/sessionuserround/?format=json</code></p>
