docs: Returns the next precomposed Unicode character.
  Repeated calls to <tt>next</tt> return all of the precomposed characters defined
  by Unicode, in ascending order.  After all precomposed characters have
  been returned, {@link #hasNext} will return <tt>false</tt> and further calls
  to <tt>next</tt> will return {@link #DONE}.
