title: BigInteger to String according to ASCII
body: <p>Is there a way to convert a series of integers to a String according to the ASCII table.  I want to take the ASCII value of a String and convert it back to a String. For example,</p>
  
  <pre><code>97098097=&gt; "aba"
  </code></pre>
  
  <p>I really need an effective way of taking an integer and converting it to a String according to its ASCII value.  This method must also take into account the fact that there is <code>no zero</code> in front of the <code>'9'</code> when the String <code>"aba"</code> has an ASCII value of <code>97098097</code> as <code>'a'</code> has an ASCII value of <code>097</code> and a String <code>"dee"</code> has one of <code>100101101</code>.  This means that not every number will have an ASCII value that has a number of digits that is a multiple of three.  </p>
  
  <p>If you have any misunderstandings of what I'm trying to do please let me know.</p>
