title: Redact content in Word document
body: <p>I need a way of "redacting" content in a word document.
  At first I tried changing the range's background color to match the foreground color, and it looks great.</p>
  
  <p>...but the text is still there. And can be copy/pasted, and the background color can still be changed back so the text is readable again.
  Especially if the document is saved as a PDF this is easy. Just copy/paste the text into notepad, and everything is readable.</p>
  
  <p>So not very secure :-(</p>
  
  <p>So I need a way of changing the content to something else, so i can't just be changed back. Maybe shapes or other characters, like x'es. But this change must not move anything else in the document - it has to take up the same amount of space.</p>
  
  <p>It doesn't HAVE to be entire black bars like in the screenshots below, blacking each word would be okay too if that's easier, leaving the spaces between words visible.</p>

  <p>It would be nice to be able to redact pictures in the document aswell, but for now text is my main focus.
  I suspect images would be easier, since they can most likely just be replaced by black shapes.</p>
