title: How to specify the character set in the HTTP Content-Type response header?
body: <p>I had my site tested with the <a href="https://developers.google.com/pagespeed" rel="noreferrer">Page Speed</a> app from Google and one of the suggestions was to specify the character set in the HTTP Content-Type response header claiming it was better than just in a meta tag.</p>
  
  <p>Here's what I understand I need to write:
  Content-Type: text/html; charset=UTF-8</p>
  
  <p>..but where exactly should I put this? I'm on a shared server.</p>
  
  <p>Thank you!</p>
