A. ISO/IEC 10646 Compatibility Table
In some existing ISO/IEC 10646-compliant systems, the code points in the UDAs of Big-5 are directly mapped to the PUA of ISO/IEC 10646 although all of the HKSCS-2008 characters concerned are already defined in ISO/IEC 10646:2003 and its Amendment 1.
In order to maintain backward compatibility with such systems, the PUA code points of those HKSCS-2008 characters which are already defined in ISO/IEC 10646 are not reassigned to other characters and are reserved as compatibility points.
Moreover, most of the HKSCS-2008 characters defined in the PUA of ISO/IEC 10646-1:1993 or ISO/IEC 10646-1:2000 have become standard characters in ISO/IEC 10646:2003.
The compatibility points can also maintain backward compatibility between versions of ISO/IEC 10646.
