title: hexdump output order
body: <p>I am playing with the Unix hexdump utility. My input file is UTF-8 encoded, containing a single character <code>ñ</code>, which is <code>C3 B1</code> in hexadecimal UTF-8.</p>
  <pre><code>hexdump test.txt
  0000000 b1c3
  0000002
  </code></pre>
  <p>Huh? This shows <code>B1 C3</code> - the inverse of what I expected! Can someone explain?</p>
  <p>For getting the expected output I do:</p>
  <pre><code>hexdump -C test.txt
  00000000  c3 b1                                             |..|
  00000002
  </code></pre>
  <p>I was thinking I understood encoding systems.</p>
