That bidi utility has known defects in it. It is not yet conformant with 
changes to UBA 6.3, let alone later changes to UBA. And the mapping of 
memory position to display position in that utility does not take into 
account complex mapping that has to occur in the layout engines and 
fonts in real applications.
