If you want to use old fashoned emoticons....click on "font style"  in the toolbar.  There at the bottom (just above the "other font" notation)  you see wingdings.  
  
 JKL
 Font style:WingDings
 Keystroke, Shift&J=J
 Keystroke Shift&K=K
 Keystroke Shift&L=L
  
 Click on wingdings, then hold your shift key and type j = J
  
 You can color them, or enlarge them.  There is a whole keyboard full of them, for your viewing pleasure.  Just play around.  Webdings are there too!

 I found this at community feedback.  I think free2play posted it.
