WG2

Welcome to WG2 web site @Unicode.

Convenor: Michel Suignard (michel@unicode.org)

ISO/IEC JTC1/SC2/WG2 is the international standardization working group for the coded character set UCS - the Universal Multiple-Octet Coded Character Set - ISO/IEC 10646. The scope is to develop a universal multiple-octet coded character set that encompasses the world's scripts. ISO/IEC 10646 and the Unicode Standard share the same repertoire, the Unicode Standard containing more implementation guidelines and documentation concerning the various writing systems encoded in the two standards. Various elements, such as the History, Timeline, and Synchronization points between the two standards can be found in the Annex C of the Unicode Standard.

ISO/IEC 10646 Latest versions

ISO/IEC 10646 latest versions and their published amendments are typically freely available on the ITTF list of Publicly Available Standards, currently:

ISO/IEC 10646:2020 (6th edition)	Published 2021-01-05
