Questions 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.

2. Which 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.

3. What 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
