title: Twig: How to get the last character in a string
body: <p>I there,</p>
  
  <p>I'm trying to find the last character for a string in twig.
  What I need to do is that if the string ends with s then I only add ' Zone and if the string doesn't have an s at the end I should add 's Zone.</p>
  
  <p>E.g., "Charles's Zone" should become "Charles' Zone".</p>
  
  <p>Thanks a lot</p>
