title: Java: String to byte array conversion
body: <p>I am getting some unexpected results from what I thought was a simple test.  After running the following:</p>
  
  <pre><code>byte [] bytes = {(byte)0x40, (byte)0xE2, (byte)0x56, (byte)0xFF, (byte)0xAD, (byte)0xDC};
  String s = new String(bytes, Charset.forName("UTF-8"));
  byte[] bytes2 = s.getBytes(Charset.forName("UTF-8"));
  </code></pre>
  
  <p>bytes2 is a 14 element long array nothing like the original (bytes).  Is there a way to do this sort of conversion and retain the original decomposition to bytes?</p>
