title: Which emoji can be used as variables in Java, visible in Eclipse?
body: <p><em>This question might be related to <a href="http://xkcd.com/1513/">today's XKCD</a>.</em></p>
  
  <p>I discovered today that emoji could be used in variable names.</p>
  
  <pre><code>int ಢ_ಢ = 42; //apparently something valid
  </code></pre>
  
  <p>Out of curiosity, is there a list of such special characters which can be used in Java, and in a way which is readable by Eclipse?</p>
