title: "Match a literal character", or "match a character literally"?
body: <p>I was making a RegEx using the <a href="http://regex101.com/" rel="noreferrer">regex101 tool</a> and read in the explanation field</p>
  
  <p><code>[.]</code> - the literal character <code>.</code></p>
  
  <p><code>[\.]</code> - matches the character <code>.</code> literally</p>
  
  <p>I get lost between "literal character" and "character literally".
  What is the difference between these two?</p>
