title: =?ISO-8859-1 in mail subject
body: <p>I'm acquiring the unread mails I have in my GMail account through PHP and its method <em>imap_open</em></p>
  
  <p>When I get the subjects through the method <em>imap_fetch_overview</em> I get some subjects like this:</p>
  
  <pre><code>=?ISO-8859-1?Q?Informaci=F3n_Apartamento_a_la_Venta?= =?ISO-8859-1?Q?_en_Benasque(Demandas:_0442_______)?=
  </code></pre>
  
  <p>It's unreadable, I think because of its character encoding.</p>
  
  <p>What should I do to make it readable?</p>
