title: Email from website form with Cyrillic characters
body: <p>I have a webpage with a form for Russian people but, for example, if I insert this Cyrillic string:</p>
  
  <p><code>Данные для трансфера</code></p>
  
  <p>into one field and send the message, when I receive the email I have this string instead </p>
  
  <p><code>Äàííûå äëÿ òðàíñôåðà</code>.</p>

  <pre class="lang-php prettyprint-override"><code>$headers .= "MIME-Version: 1.0"."\r\n" ."Content-type: text/plain; charset='utf-8'". "\r\n";
  </code></pre>
