CJK Unified Ideographs Extension D

Unicode character block

(2010)222 (+222) Unicode documentationCode chart ∣ Web pageNote: ^[1]^[2]

CJK Unified Ideographs Extension D is a Unicode block containing uncommon CJK ideographs for Chinese, Japanese, Korean, and Vietnamese, some of which are in current use. Much smaller than most Unicode blocks for CJK unified ideographs, Extension D consists of characters which were submitted to the Ideographic Research Group as "urgently needed characters" between 2006 and 2009. Characters submitted during the same period which were needed less urgently were included in CJK Unified Ideographs Extension E instead.^[3]

The block has hundreds of ideographic variation sequences registered in the Unicode Ideographic Variation Database (IVD).^[4]^[5] These sequences specify the desired glyph variant for a given Unicode character.
