Han Unification in UNICODE:
===========================

One major challenge in creating code elements is accommodating the many
thousands of ideographs used in Chinese, Japanese, and Korean text(called
CJK text for short). ... ...
In China, they are called Hanzi; in Korea, Hanja; in Japan, Kanji.

Current national standards for ideographs in Japan, China, Korea, and Taiwan
define a totoal of more than 31,000 ideographs used for written text in theses
countries.

The Unicode standard uses Han unification to consolidate Chinese, Korea, and
Japanese ideographs.

The CJK Joint Research Group has identified and categorized over 11,000
duplicate ideographs in a process call Han unification. By minimizing the
duplication of identical ideographs in separate languages, the Han unified
character set represents all of the standard Han symbols with fewer than
21,000 unique characters.

Chinese characters in GB:
=========================

There exist the following GuoBiao for Chinese characters:
   GB 2312-80 (0)      GB 12345-90 (1)
   GB ??-8?   (2)      GB 7589-87  (3)
   GB ??-8?   (4)      GB 7590-87  (5)
   ?                   ?
   GB 8565-89 (8)      ?

GB.1 contains all characters in GB.0 in traditional form, including those
different characters which have the same simplied form. The same charater
(which has not been simplified) in GB.0 and GB.1 are in same position,
the traditional form and the simplified form of the same are also in same
position if the correspondence is one-to-one.

Each of GB.2 and GB.4 contains more than 6,000 Chinese charaters. GB.3 and
GB.5 are corresponce (like GB.1 and GB.0) of GB.2 and GB.4, respectively.

GB.6 and GB.7? I forgot the exact information.

Simplified and traditional Han characters in UNICODE:
=====================================================

Both of the following simplified character and traditional characters are
contained in Unicode (in different position):

 \    ------
---    _|__
  |   __|__|
  |    ____
  |/  |____|

 \    ------
---    _|__
--    __|__|
---    ____
 __   |    |
|__|  |____|

The following simplified form and traditional form are regarded as the same
one in Unicode:

___|_____|___
   |     |
  __________
 |__________|
 |__________|
      |
______|______
      |
      |

#
#   General notes:
#
#   This table contains the the mappings between the Unicode
#       Han ideographic character set (Unihan) and various
#       national and industrial standards
#
#   Format:
#       There are 10 tab-separated fields, one for each set mapped.
#       These fields are ordered as follows:
#
#       Unicode:
#           4 digit hexadecimal code, beginning at U4E00.
#       GB:
#           5 digit decimal.
#               Digit 1 is the GB subset.
#               Digits 2 to 5 are the code in row/column format.
#           The GB subsets are:
#               0 = GB 2312-80.
#               1 = GB 12345-90.
#               3 = GB 7589-87.
#               5 = GB 7590-87.
#               7 = General Purpose Han Characters for Modern Chinese.
#               8 = GB 8565-89.
#       Big 5:
#           4 digit hexadecimal.
#       CNS:
#           5 digit hexadecimal.
#               Digit 1 indicates a subset of CNS 11643-1986.
#               Digits 2 to 5 are the code in interchange format.
#           The CNS subsets are:
#               1 = Primary.
#               2 = Less frequent characters.
#               E = User characters.
#      JIS:
#          5 digit decimal.
#              Digit 1 is the JIS subset.
#              Digits 2 to 5 are the code in row/column format.
#          The JIS subsets are:
#              0 = JIS X0208-1990.
#              1 = JIS X0212-1990.
#              I = IBM extensions (4 digit hexadecimal).
#      KSC:
#          5 digit decimal.
#              Digit 1 is the KSC subset.
#              Digits 2 to 5 are the code in row/column format.
#          The KSC subsets are:
#              0 = KSC 5601-1987.
#              1 = KSC 5657-1991
#              2 = IBM extensions (4 digit hexadecimal).
#      ANSI Z39.64-1989 (EACC):
#          6 digit hexadecimal.
#      CCCII, level 1:
#          6 digit hexadecimal.
#      Xerox:
#          7 digit octal, with a colon separating each byte.
#      Fujitsu:
#          4 digit hexadecimal JEF code.
#
#      NOTES:
#
#      The mappings in this table between Unicode and GB, CNS, JIS and KSC
#      have been compared to the mapping information provided by the CJK-JRG,
#      which has exhaustively checked and rechecked.  The mappings for these
#      characters may be taken as final and definitive.
#
#      The mappings in this table between Unicode and Big 5, EACC, CCCII, Xerox,
#      IBM and Fujitsu have not been so exhaustively checked.  There may still
#      be errors in these mappings.  Final and authoritative mappings for these
#      character sets will be provided in the near future.  Please notify
#      [email-masked] of any errors.
#
#      Empty fields contain the single character '*'.
