title: Php email sent with issues on subject chars in Outlook only
body: <p>Im sending a mail using php, and the subject of the mail has accents.</p>
  
  <p>Im receiving weird characters in Outlook instead the accented chars. If i see the email in a web email client i see the subject perfect.</p>
  
  <p>This is the code that im using to send the email:</p>
  
  <pre><code>$to  = 'whateveremail@whatever.com';
  
  $subject = '[WEBSITE] áccent – tésts';
  
  $message = '&lt;p&gt;Test message&lt;/p&gt;
  
  $headers = 'MIME-Version: 1.0' . "\r\n";                                          
  
  $headers.= 'From:equipothermomix@thermomix.com' . "\r\n";                                   
  
  $headers.= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
  
  mail($to, $subject, $message , $headers);
  </code></pre>
  
  <p>How i could solve the issue, do i have to use another charset?</p>
