International Organization for Standardization (ISO), International Electro-technical Commission (IEC ) which is subordinate to UN and Join Technical Committee One (JTC1)which was the first join technical committee co-organized by ISO and IEC under mutual agreement, are responsible for establishing international standards in connection with information handlings and information technologies; ISO/IEC JTC1/SC2 is the second sub-committee (Sub-Committee 2) subordinate to JTC1, it takes charge of standardizing internal codes of different language symbol sets; while ISO/IEC JTC1/SC2/WG2 is the second working group (Working Group Two) subordinate to ISO/IEC JTC1/SC2.


ISO established the working group of ISO/IEC JTC1/SC2/WG2 (WG2) to accommodate a variety of characters and symbols of languages used in the world. WG2 is responsible for setting up and retaining the encoding standard of new international character sets - Universal Multiple-Octet Coded Character Set(UCS);The number is assigned ISO/IEC 10646 (ISO 10646) in hope to solve difficulties such as unable to interchange character information, unable to globalize operation system and software application among nations. WG2 meet twice a year in principle to discuss the various revisions related to ISO/IEC 10646.


The “Ideographs agreed by China, Japan and Korea” of ISO/IEC 10646 gather Chinese characters used by Asian countries. As the scale of Chinese characters is enormous and is often shared by many countries (areas), therefore WG2 again organized “Ideograph Rapporteur Group (IRG)” which is in charge of collecting, comparing, and sorting Chinese character sets used in different countries then forward the information to WG2 for coding. IRG meet twice a year and members are from China, Hong Kong, Macau, Taipei Computer Association, Singapore, Japan, South Korea, North Korea, Vietnam and USA. Unicode Consortium also sent representatives to the meetings for discussing the works of collecting and arranging Chinese characters (including modern and ancient Chinese) used in different countries.
