title: find and delete files with non-ascii names
body: <p>I have some old migrated files that contain non-printable characters. I would like to find all files with such names and delete them completely from the system.</p>
  
  <p>Example: </p>
  
  <pre><code>ls -l
  -rwxrwxr-x 1 cws cws      0 Dec 28  2011 ??"??
  
  ls -lb
  -rwxrwxr-x 1 cws cws      0 Dec 28  2011 \a\211"\206\351
  </code></pre>
  
  <p>I would like to find all such files.</p>
  
  <p>Here is an example screenshot of what I'm seeing when I do a <code>ls</code> in such folders:</p>

  <p>I want to find these files with the non-printable characters and just delete them.</p>
