title: Does NSUTF16LittleEndianStringEncoding make a byte array
body: <p>I need to encrypt a string.  The service that I am sending it to requires that it be an MD5 hash of the byte array of the string in UTF16LE.</p>
  
  <p>Basically: if I have <code>myString</code> that needs to be put into a UTF16LE byte array, and then that array needs to be MD5 Hashed.</p>
  
  <p>Does NSUTF16LittleEndianStringEncoding actually make the byte array?  I can't tell from the documentation if that's what is going on.
  If it does not, does anyone have a good way to create a byte array form a sting with UTF16LE encoding?
  I've tried using <code>getBytes</code>, and [myString bytes] and <code>const char</code> and I still am striking out.  Admittedly there is something I don't understand but the documentation @dev.apple is not shedding any light that I can see.
  Note: I asked a similar question the other day but I have since found out more information about what they want.</p>
  
  <p>Thanks</p>
