title: Integer ASCII value to character in BASH using printf
body: <p>Character to value works:</p>
  
  <pre><code>$ printf "%d\n" \'A
  65
  $ 
  </code></pre>
  
  <p>I have two questions, the first one is most important:</p>
  
  <ul>
  <li>How do I take 65 and turn it into A?</li>
  <li>\'A converts an ASCII character to its value using printf. Is the syntax <em>specific</em> to <em>printf</em> or is it used anywhere else in BASH? (Such small strings are hard to Google for.)</li>
  </ul>
