title: How do you enter a tab character in Textblock?
body: <p>Is it possible to add a tab character into a textblock?
  It's a textblock in Xaml, but i'm adding the text in code, so it has to be done there.
  Is there any action like "Environment.NewLine", but for the "Tab" character?</p>
  
  <p>Thanks in advance.</p>
