Ideographic Research Group
The Ideographic Research Group (IRG), formerly called the Ideographic Rapporteur Group, is a subgroup of Working Group 2 (WG2) of ISO/IEC JTC 1/SC 2 (SC 2), the subcommittee of the Joint Technical Committee of ISO and IEC which is responsible for developing standards within the field of coded character sets. IRG is composed of experts from China, Japan, South Korea, Vietnam and other countries and regions that use Han characters, as well as experts representing the Unicode Consortium. The group is responsible for coordinating the addition of new CJK unified ideographs to the Universal Multiple-Octet Coded Character Set (ISO/IEC 10646) and the Unicode Standard. The group meets twice a year for 4-5 days each time, and reports its activity to the subsequent meeting of WG2. History The precursor to the Ideographic Rapporteur Group was the CJK Joint Research Group (CJK-JRG), which was established in 1990. In October 1993 this group was established as a subgroup of WG2 under SC2 with ...

ISO/IEC JTC 1/SC 2
ISO/IEC JTC 1/SC 2 Coded character sets is a standardization subcommittee of the Joint Technical Committee ISO/IEC JTC 1 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), that develops and facilitates standards within the field of coded character sets. The international secretariat of ISO/IEC JTC 1/SC 2 is the Japanese Industrial Standards Committee (JISC), located in Japan. SC 2 is responsible for the development of the Universal Coded Character Set (ISO/IEC 10646) which is the international standard corresponding to the Unicode Standard. History ISO/IEC JTC 1/SC 2 was established in 1987, originally with the title “Character Sets and Information Coding,” with the area of work being, “the standardization of 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 proc ...

Singapore
Singapore (), officially the Republic of Singapore, is a sovereign island country and city-state in maritime Southeast Asia. It lies about one degree of latitude () north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south, the South China Sea to the east, and the Straits of Johor to the north. The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet; the combined area of these has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the third highest population density in the world. With a multicultural population and recognising the need to respect cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the lingua franca and numerous public services are available only i ...

CJK Compatibility Ideographs
CJK Compatibility Ideographs is a Unicode block created to contain Han characters that were encoded in multiple locations in other established character encodings, in addition to their CJK Unified Ideographs assignments, in order to retain round-trip compatibility between Unicode and those encodings. Such encodings include the South Korean KS X 1001:1998 (U+F900–U+FA0B, 268 characters), Taiwanese Big5 (U+FA0C–U+FA0D, 2 characters), Japanese IBM 32 ( CP932 variant; U+FA0E–U+FA2D, 32 characters), South Korean KS X 1001:2004 (U+FA2E–U+FA2F, 2 character), Japanese JIS X 0213 (U+FA30–U+FA6A, 59 characters), Japanese ARIB STD-B24 (U+FA6B–U+FA6D, 3 characters) and the North Korean KPS 10721-2000 (U+FA70–U+FAD9, 106 characters) source standards. In ensuing versions of the standard, more characters have been added to the block. These even include a few regular ideographs (with the Unified_Ideograph property) that do not have duplicates (U+FA ...

CJK Unified Ideographs (Unicode Block)
CJK Unified Ideographs is a Unicode block containing the most common CJK ideographs used in modern Chinese, Japanese, Korean and Vietnamese characters. When compared with other blocks containing CJK Unified Ideographs The Chinese, Japanese and Korean (CJK) scripts share a common background, collectively known as CJK characters. In the process called Han unification, the common (shared) characters were identified and named CJK Unified Ideographs. As of Unicode ..., it is also referred to as the ''Unified Repertoire and Ordering'' (URO). The block has hundreds of variation sequences defined for standardized variants. It also has tens of thousands of ideographic variation sequences registered in the Unicode Ideographic Variation Database (IVD). These sequences specify the desired glyph variant for a given Unicode character.
