title: include figures with multiple spaces in the filename
body: <p>I have lots of files with name format <code>case1_test     2_4.png</code>. For some reasons, I can not remove the spaces from those filenames. Can anyone suggest how to include this kind of file using includegraphics.</p>
  
  <p>I have tried several solutions including griffle package and double quotations. However none of them works.</p>
  
  <p>Tried suggestions from this page
