title: Change "Quoted-printable" encoding to "utf-8"
body: <p>I am trying to read email with imaplib. I get this mail body:</p>
  
  <pre><code>=C4=EE=E1=F0=FB=E9 =E4=E5=ED=FC!  
  </code></pre>
  
  <p>That is <code>Quoted-printable</code> encoding.<br>
  I need to get <code>utf-8</code> from this. It should be <code>Добрый день!</code></p>
  
  <p>I googled it, but it is too messy with Python's versions. It is already unicode in Python 3, I cann't use <code>.encode('utf-8')</code> here. </p>
  
  <p>How can I change this to <code>utf-8</code>?  </p>
