Unicode Version 17.0
曹
U+66F9 "曹" CJK Unified Ideograph-# is a Chinese character used in multiple East Asian languages, including Mandarin, Japanese, and Korean, where it carries historical and linguistic significance. In modern Chinese, it often functions as a surname, famously associated with figures like Cao Cao, the influential warlord from the Three Kingdoms period, and also appears in words meaning "a class" or "a grade," such as in "de cao" for moral quality. The character is composed of the radical for "one" or "cover" and a phonetic component, and its usage extends to historical references, like the ancient state of Cao during the Zhou dynasty, as well as in Japanese for the word "kusa" in some contexts.
