title: Eclipse: I turned on hidden characters now I can't turn off
body: <p>Somehow I've turned on hidden characters in Eclipse. It's not the "whitespace" characters in the general editor preferences. When turned on, it adds another layer of hidden characters over the existing ones.</p>
  
  <p>Then I have things like </p>
  
  <blockquote>
    <blockquote>
      <p>\r\n</p>
    </blockquote>
  </blockquote>
  
  <p>Does anyone know what these are and how to remove them?</p>
