title: Behaviour of GNU sort command (with non-letter ASCII characters, such as dot or semicolon)
body: <p>I want the <code>sort</code> command to treat all characters equal.</p>
  
  <p>For example, when I do</p>
  
  <pre><code>$ echo -e 'TEST.b\nTESTa\nTESTc' | sort
  TESTa
  TEST.b
  TESTc
  </code></pre>
  
  <p>the dot is ignored.</p>
  
  <p>I would like to get <code>TEST.b</code> at the last or first position. However, I cannot find the proper parameter in the manual page.</p>
  
  <p>(my version of <code>sort</code> is from the GNU core utilities).</p>
