title: What is <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />?
body: <p>When I create a new Html file in Visual Studio 2017, this:</p>
  
  <pre><code>&lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;
  &lt;meta charset="utf-8" /&gt;
  </code></pre>
  
  <p>always shows up in the <code>&lt;head&gt;</code>.</p>
  
  <p>The program works just fine without it. So, can someone please tell me what it does?</p>
