The Ideographic Rapporteur Group (IRG)[1] is a subgroup of the ISO/IEC JTC 1/SC 2 working group WG2.


IRG is responsible for reviewing proposals for adding new CJK unified ideographs to the Universal Multiple-Octet Coded Character Set (ISO/IEC 10646) and the Unicode Standard, and submitting consolidated proposals for sets of CJK unified ideographs to WG2, which are then processed for encoding in the ISO/IEC 10646 and Unicode standards by SC2 and the Unicode Technical Committee respectively.[2][3] National and liaison bodies of SC2 that participate in IRG include China, Hong Kong, Japan, North Korea, South Korea, Macau, Singapore, Taipei Computer Association, Unicode Consortium, United Kingdom, and Vietnam.

As of Unicode version 11.0, the IRG has been responsible for submitting several blocks of CJK unified ideographs and compatibility ideographs for encoding:[4]
