title: PHP 5.6 update makes UTF-8 not work
body: <p>I have recently updated my PHP-Webspace to 5.6 (from 5.5) and something strange happened. My website suddenly displays UTF-8 characters incorrectly eventhough I am using the Meta Tag <code>&lt;meta charset="utf-8"&gt;</code> and following line in my .htaccess file <code>AddDefaultCharset utf-8</code>.</p>
  
  <p>After inserting following line in my PHP-Script everything worked again <code>header('Content-Type: charset=utf-8');</code>.</p>
  
  <p>This both happened on my Webspace (where I don't have access to the php.ini file) and my local server. As I am also using other PHP scripts, I don't want to insert <code>header('Content-Type: charset=utf-8');</code> into all config files...</p>
  
  <p>What could be the cause?</p>
