CJK Unified Ideographs
![](http://upload.wikimedia.org/wikipedia/commons/thumb/b/b2/CJKV_variant_glyphs.png/330px-CJKV_variant_glyphs.png)
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 14.0, Unicode defines a total of 92,865 CJK Unified Ideographs.[1]
The terms ideographs or ideograms may be misleading, since the Chinese script is not strictly a pictographic or ideographic system.
Historically, Vietnam used Chinese ideographs too, so sometimes the abbreviation CJKV is used. This system was replaced by the Latin-based Vietnamese alphabet in the 1920s.
CJK Unified Ideographs blocks[]
CJK Unified Ideographs[]
The basic block named CJK Unified Ideographs (4E00–9FFF) contains 20,992 basic Chinese characters in the range U+4E00 through U+9FFF. The block not only includes characters used in the Chinese writing system but also kanji used in the Japanese writing system and hanja, whose use is diminishing in Korea. Many characters in this block are used in all three writing systems, while others are in only one or two of the three. Chữ Hán are also used in Vietnam's chữ Nôm (now obsolete). The first 20,902 characters in the block are arranged according to the Kangxi Dictionary ordering of radicals. In this system the characters written with the fewest strokes are listed first. The remaining characters were added later, and so are not in radical order.
The block is the result of Han unification,[2] which was somewhat controversial within East Asia.[3] Since Chinese, Japanese and Korean characters were coded in the same location, the appearance of a selected glyph could depend on the particular font being used. However, the source separation rule states that characters encoded separately in an earlier character set would remain separate in the new Unicode encoding.[4]
Using variation selectors, it is possible to specify certain variant CJK ideograms within Unicode. The Adobe-Japan1 character set, which has 14,683 ideographic variation sequences,[5] is an extreme example of the use of variation selectors.[6]

CJK Compatibility Ideographs[]
The block named CJK Compatibility Ideographs (F900–FAFF) was created to retain round-trip compatibility with other standards. Only twelve of its characters have the "Unified Ideograph" property: U+FA0E, FA0F, FA11, FA13, FA14, FA1F, FA21, FA23, FA24, FA27, FA28 and FA29.[1] None of the other characters in this and other "Compatibility" blocks relate to CJK Unification.

UTC Sources[]
The Ideographic Research Group (IRG) bears the formal responsibility of developing extensions to the encoded repertoires of unified CJK ideographs. The Unicode Consortium participates in this group as a liaison member of ISO. The characters submitted by the Unicode Technical Committee bear the prefix "UTC". All CJK Unified Ideographs in ISO/IEC10646 are required to have at least one source identifier. Changes to IRG source information, however, can leave a given ideograph without any such sources. In such cases, the ideograph is included in the U-source database to guarantee it has at least one source. Such ideographs are indicated by a source prefix of "UCI" instead of "UTC".[10]
The UTC sources consist of the following:
- ABC Chinese-English Dictionary by John DeFrancis
- The Adobe-CNS1 glyph collection
- The Adobe-Japan1 glyph collection
- A Complete Checklist of Species and Subspecies of Chinese Birds (中国鸟类系统检索)
- The Great Nom Dictionary (Đại Tự Điển Chữ Nôm)

Disunification[]
U+4039[]
The character U+4039 (䀹) was a unification of two different characters (one with jiā 夾 phonetic and one with shǎn 㚒 phonetic) until Unicode 5.0. However, they were lexically different characters that should not have been unified; they have different pronunciations and different meanings.
The proposal of disunification of U+4039[11] was accepted and the new character is encoded at U+9FC3 (鿃) in Unicode 5.1.[clarification needed]
Other 3 glyphs in Extension B[]
In CJK Unified Ideographs Extension B, some characters are incorrectly unified with others. These characters include U+2017B (
