title: Show whitespace characters in Visual Studio Code
body: <p>Is it possible to show whitespace characters, like the space character, in Visual Studio Code? </p>
  
  <p>There doesn't appear to be an option for it in the <code>settings.json</code> (though it is an option in <em>Atom.io</em>), and I haven't been able to display whitespace characters using CSS.</p>
