Unicode Extends Chinese, Japanese, Korean (CJK)
Version 4.0.1 of the Unicode® Standard Released
Mountain View, CA, March 31, 2004 — The Unicode® Consortium
announced today a new update of the Unicode Standard,
Version 4.0.1, a significant revision of its Unicode Character Database, widely
used in software products. No new characters are added to the standard at this
time—the total number of characters still stands at 96,382 for the world's
scripts and collections of symbols. However, the information in the Character
Database has been refined to improve the quality of text processing in all
languages of the world.
This version of the Unicode Character Database includes the first major
update of the CJK database (Unihan) in two years. The Unihan Database provides character properties, definitions,
pronunciations, mappings, and other information for the CJK characters in the
standard—the characters used in particular for Chinese, Japanese, and Korean.
This update includes thousands of additions and corrections, including major new correlations with traditional
Chinese and Japanese dictionary sources.
This version of the Unicode Standard significantly improves the ability to
interchange languages such as Arabic, Hebrew, Urdu, and
Pashto. It also clarifies the implementation of such languages as
Bengali and the relationship between base form letters and accent marks.

4.0.1 are published online at

Version 4.0.1 amends, was published by Addison-Wesley in
September of 2003 (ISBN 0-321-18578-1). For full information,
