Revision March 2017

Scope:    Standardization of graphic character sets and their characteristics, including string ordering, associated control functions, their coded representation for information interchange and code extension techniques. Excluded: audio and picture coding.

History

1961       Established as a working group of ISO/TC 97 (ISO/TC 97B: Character sets and coding) at the 1st Plenary Meeting of ISO/TC 97.

1962       Renamed to ISO/TC 97/SC 2 at the 2nd Plenary Meeting of ISO/TC 97.

1987       Establishment of JTC 1/SC 2 (transferred from ISO/TC 97/SC 2).  The title was ” Character sets and information coding” and the Area of work was “The standardization of the bit and byte coded representation of information for interchange including among others, sets of graphic characters, of control functions, of picture elements and audio information coding of text for processing and interchange; code extension techniques; implementation of these coded representations on interchange media and transmission systems”.  The Secretariat was AFNOR and the Chairman was Mr. Jean Dubos.  The working groups existed were: WG 1: Code Extension Techniques [Convenor: Mr. Dara Hekimi], WG 2: Multiple-octet Coded character set [Convenor: Mr. Jerry J. Andersen], WG 3: 7-bit and 8-bit Codes [Convenor: Mr. Dara Hekimi], WG 6: Control Functions [Convenor: Mr. Joachim Friemelt] and WG 8: Coded Representation of Picture and Audio Information [Convenor: Dr. Hiroshi Yasuda].

1988-10  Mr. Bernard Marti was endorsed as its Chairman. Mr. Mike Ksar was appointed as the WG 2 Convenor.  SC 2 recommended JTC 1 to establish a new SC to which the functions and activities of SC 2/WG 8 were transferred. Pending the formation of the new SC, SC 2 redefined the terms for reference of WG 8 and raised the subgroups of WG 8 to Working Group status.  As a result, Working Groups 7 to 12 were created.

1991-10  The title and scope were modified.  The new title was “Coded Character Sets” and scope was “Standardization of graphic character sets and their characteristics, associated control functions, and their coded representation for information interchange; excluding audio and picture coding”. WG 1 and WG 6 were disbanded and their projects were re-assigned to WG 3.  The terms of reference of WG 2 and WG 3 were updated. Mr. J. van den Beld was appointed as the WG 3 Convenor.  Working Groups 7 to 12 were terminated and their activities were transferred to JTC 1/SC 29.

1994-02  Mr. Sten Lindberg was appointed as the SC 2 Chairman.  The scope was modified to “Standardization of graphic character and their characteristics, associated control functions, their coded representation for information interchange, and code extension techniques. Excluded: audio and picture coding.
