title: Whats the use of <meta http-equiv="content-type" content="text/html; charset=UTF-8">
body: <p>Is it still necessary/beneficial to use the following ancient meta tag in the head, or is it obsolete? What purpose does this sentence offer and it safe to remove it?</p>
  
  <p><code>&lt;meta http-equiv="content-type" content="text/html; charset=UTF-8"&gt;</code></p>
  
  <p>I already have <code>AddDefaultCharset UTF-8</code> in my .htaccess file; <code>&lt;!doctype html&gt;</code> on the top of my webpage and <code>header('Content-type: text/html; charset=utf-8');</code> in the head of my php generated html webpage [index.php]</p>
  
  <p>I need full mobile/desktop coverage for the major browsers like IE9+, FireFox20+, Edge, Chrome, Safari, etc for browsers on pc mac linux android and iphones of say at most 5 years old, today and the future. Thanks</p>
