title: Django + MySQL - Unknown encoding: utf8mb4
body: <p>MySQL 5.5.35
  Django 1.6.1</p>
  
  <p>In order to support emoticons in the DB, I have configured in my django settings:</p>
  
  <pre><code>'OPTIONS': {'charset': 'utf8mb4'}
  </code></pre>
  
  <p>On MySQL connection, I get this error:
  LookupError: unknown encoding: utf8mb4</p>
  
  <p>How should I configure Django/MySQL in order to support utf8mb4?</p>
