about Ideograph Characters
1. How to unify Han?
The unification criteria employed in the original Unicode Han character
repertoire were based on rules used by JIS and on a set of Han character
identity principle (rentong yuanze) being developed in China by
experts working with the Association for a Common Chinese Code (ACCC).
At the meeting was held in Seoul in February 1990, it emerged the
Chinese/Japanese/Korean Joint Research Group (CJK-JRG) to study
a unified Han encoding.
are the source dictionaries for Han unification?
The source dictionaries for Han unification include, KangXi Zidian,
Dai Kan-Wa Jiten, Hanyu Da Zidian, and Dae Jaweon.
is CJK Ideographs Unification?
The ideographs in the ISO/IEC 10646 are derived from the source
standards by applying a set of unification procedures. The purpose
is to avoid giving multiple code points to CJK ideographs that are
basically the same with slight variation in shape. Ideographs that
are unrelated in historical derivation have not been unified. An
association between ideographs from different sources is made here
if their shapes are sufficiently similar, according to the two-level
classification to differentiate (a) between abstract shapes and
(b) between actual shapes determined by particular typefaces
