title: What is this strange whitespace in SublimeText
body: <p>In SublimeText2, some of my whitespace behaves strangely.</p>
  
  <p>For example, I I select the contents of a script (as shown in the screenshot below), and do <kbd>shift</kbd>+<kbd>tab</kbd> (to reduce indentation) it only works on the lines with <em>normal</em> spacing, resulting in my code indentation becoming all wonky.</p>
  
  <p><strong>Notes:</strong></p>
  
  <ul>
  <li>the <em>non-space</em> white spaces are <em>not</em> tabs, </li>
  <li>it's set to indent using spaces</li>
  <li>doing "<em>convert tabs to spaces</em>" has no effect. </li>
  <li>My settings file has: <code>"draw_white_space": "all",</code></li>
  </ul>
  
  <p>I think this only happens with code pasted from elsewhere (like oneNote), and the only way I've found to deal with it is to manually replace the spacing with actual spaces.</p>
  
  <p>Does anyone have an explanation for this behavior or a way to better deal with it?</p>
