title: How to display unicode control characters in visual studio text visualizer?
body: <p>I get some text string from service, which contains Unicode control characters
  (i.e <code>\u202B</code> or <code>\u202A</code> and others for Arabic language support).</p>
  
  <p>But while debugging I can't see them in default text visualizer. So I need to enable display for such characters to determine which of them my text consists of. There is checkbox in text visualizer "show all characters", but it doesn't work as I expect.</p>
  
  <p>Any suggestions?</p>
  
  <p>Thanks in advance</p>
