title: Unicode in Android
body: <p>i have a little problem by printing the complement symbol in android.</p>
  
  <pre><code> char c = '\u2216'; 
   // should be the unicode for complement
   textView2.setText(c); 
   // gives out "" nothing
   // if i take
   c = '\u2229'
   // it works
  </code></pre>
  
  <p>But why i cant print out the complement symbol, where is the mistake ?
  if someone has a solution, it would be very nice to shar it. Thanks !</p>
