Ideographic Rapporteur Group

The Ideographic Rapporteur Group (IRG) advises the Unicode Consortium and the ISO/IEC JTC1/SC2/WG2 on Han character additions to the repertoire of the Unicode and ISO/IEC 10646-1 (Universal Multiple-Octet Coded Character Set) character set standards, and on Han unification. The working members of the IRG are either appointed by member governments, or are invited experts from other countries. IRG members include Mainland China, Hong Kong, Macau, Taipei Computer Association, Singapore, Japan, South Korea, North Korea, Vietnam and United States.

The IRG has contributed several blocks of characters to Unicode/UCS, including the CJK Unified Ideographs, CJK Compatibility Ideographs (and Supplement), and CJK Unified Ideographs Extensions A, B, C, D, and E. CJK Unified Ideographs Extension F is in preparation, as of Unicode 8.0.
