Unicode 2.1 was released in early 1998. The first public release was Unicode 2.1.2 in
May 1998. This was followed by updates to Unicode 2.1.5 in
August, 1998, Unicode 2.1.8 in
December 1998 and Unicode 2.1.9 in
April 1999. The previous version was
Unicode 2.0 and the next version is
Unicode 3.0.
The Unicode Consortium defines Unicode 2.1 as : The Unicode Standard, Version 2.0
Reading, MA, Addison-Wesley Developers Press, 1996. ISBN 0-201-48345-9, plus the changes enumerated in http://www.unicode.org/unicode/reports/tr8.
Although packed with revisions and changes, Unicode 2.1 adds only two new characters :
All the rest of the changes involved subtle changes in the associated character data, such as
General Category,
Bidirectional Category,
Combining Class and
Case Mapping. Below I list the changes in general and bidirectional categories, except where they become unweildy.
