Compatibility Tables

  1. 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.

  2. Big-5 Compatibility Table

    All the Government Common Character Set (GCCS) characters in the HKSCS-2008 are to retain their original code points. However, the following kinds of GCCS characters are not included in the HKSCS-2008:

    • Characters found as variants of other characters in Big-5 are unified;
    • Characters not verifiable.

    To maintain backward compatibility, the original code points occupied by these characters are still reserved in the HKSCS-2008 as compatibility points.
