U+2F00 "⼀" Kangxi Radical One Unicode Character
Unicode Version 17.0
⼀
U+2F00 "⼀" Kangxi Radical One is a graphical representation of the first of the 214 Kangxi radicals, which are the standard set of radicals used for indexing Chinese characters in traditional dictionaries. This radical, meaning "one" as a single horizontal stroke, serves as a foundational component in many complex characters, often symbolizing unity, singularity, or the beginning of numerical concepts. It is encoded in the Kangxi Radicals block of Unicode, distinct from the similar-looking CJK character "一" (U+4E00), to specifically denote the radical itself for use in linguistic and lexicographic contexts.
