title: Do I really need to encode '&' as '&amp;'?
body: <p>I'm using an '<code>&amp;</code>' symbol with HTML5 and UTF-8 in my site's <code>&lt;title&gt;</code>. Google shows the ampersand fine on its <a href="https://en.wikipedia.org/wiki/Search_engine_results_page" rel="noreferrer">SERPs</a>, as do all the browsers in their titles.</p>
  <p><a href="http://validator.w3.org" rel="noreferrer">http://validator.w3.org</a> is giving me this:</p>
  <blockquote>
  <p>&amp; did not start a character reference. (&amp; probably should have been escaped as <code>&amp;amp;</code>.)</p>
  </blockquote>
  <p>Do I really need to do <code>&amp;amp;</code>?</p>
  <p>I'm not fussed about my pages validating for the sake of validating, but I'm curious to hear people's opinions on this and if it's important and why.</p>
