title: ActionMailer non-ASCII characters
body: <p>I'm trying to send <code>text/plain</code> emails with ActionMailer that have non-ASCII characters in them. However, an email with the contents:</p>
  
  <pre><code>“This has smart quotes”
  </code></pre>
  
  <p>Displays in emails (and the logs) as:</p>
  
  <pre><code>=E2=80=9CThis has smart quotes=E2=80=9D
  </code></pre>
  
  <p>And the <code>Content-Transfer-Encoding</code> of the email is <code>quoted-printable</code>. In the view, this text is rendered like so:</p>
  
  <pre><code>&lt;%= raw(strip_tags(@message)) %&gt;
  </code></pre>
  
  <p>I'm not sure where this is happening, the <code>charset</code> header of the email is UTF-8. This is Ruby 1.9.3-p194 and Rails 3.2.11.</p>
