If you use the following to output on a plain canvas

procedure TForm1.FormPaint(Sender: TObject);
   r: TRect;
   s: String;
   r.Top := 0;
   r.Left := 0;
   r.Bottom := 50;
   r.Right := 50;
   s := 'abcdef';
   LCLIntf.ExtUTF8Out(Canvas.Handle, 10, 10, ETO_OPAQUE+ETO_CLIPPED, @r, 
@s[1], 5, nil)


Do you get the ligature?
