title: how can i get the Unicode infinity symbol converted to String
body: <p>I want to use the infinity symbol (8 lying sideways) in java.</p>
  
  <p>furthermore i want to use it as a String component.<br>
  i did not find a working charcode/ascii code for this (is there any?).</p>
  
  <p>i tried:</p>
  
  <pre><code>String s=Character.toString(236);
  String s=Character.toString('236');
  </code></pre>
  
  <p>am i missing something?</p>
  
  <p>i got this now:</p>
  
  <pre><code>System.out.println(Character.toString('\u221E'));
  </code></pre>
  
  <p>but the output is <code>?</code></p>
  
  <p>i am using java 1.7 jdk and eclipse. why is the infinity sign not showing up?</p>
