title: Char to int and back again
body: <p>I want to find an integer representation of a character, then later on find a character representation of an int. </p>
  
  <p>My current solution is this, but it doesn't work: </p>
  
  <pre><code>String s = "A"
  Integer b = Character.getNumericValue(s.toCharArray()[0]);    // 10
  char c = Character.toChars(b)[0];                             // (blank)
  </code></pre>
  
  <p>How should i do this? </p>
