          <para>
	    Note that <paramref name="offset" /> and <paramref name="n_chars" />

	    In order to use this function, you should first call
	    <see cref="M:Gtk.IMContext.GetSurrounding" />
	    to get the current context, and
	    call this function immediately afterwards to make sure that you
	    know what you are deleting. You should also account for the fact
	    that even if the signal was handled, the input context might not
	    have deleted all the characters that were requested to be deleted.
	  </para>
          <para>
	    This function is used by an input method that wants to make
	    subsitutions in the existing text in response to new input. It is
	    not useful for applications.
