Appendix -- Conversion Table for ISO-2022-CN (EXT) and Big5

   This is a conversion table for the Chinese characters in Big5's
   common part and ISO-2022-CN/-EXT, including all the vendor-specific
   characters from Eten, Microsoft and IBM.  For conversion source and
   binary programs for Big5, III provides good on-line services (ftp
   site listed in section 1.4), and [CJKINF] is also a good reference.
