Unihan-3.txt is kinda a mapping. Unfortunately, it is far from complete.

What I really care is a good approach to construct "indices" for Chinese
documents (especially, books). CCDB(Chinese Characters DataBase) of CCCII
provides some promising ways to order Chinese characters. That's why I would
like to see a complete Unihan <-> CCCII mapping.

Could you tell me where to find the draft version containing 75684
characters??? And who maintains the CCCII standard now??? I really
want to know these answers.
