U+5FC5 "必" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
必
U+5FC5 "必" CJK Unified Ideograph-# is a Chinese character that primarily means "must," "necessarily," or "certainly" and is used across multiple East Asian writing systems including Chinese, Japanese, and Korean. Its structure consists of a heart radical 心 (xin) as a base, with a stroke through the middle, symbolizing an imperative or unavoidable feeling or action. In classical texts, it often conveys logical necessity or inevitability, and it appears frequently in common compounds such as 必要 (biyao, "necessary") and 必须 (bixu, "must"). The character has deep historical roots, originating in ancient Chinese oracle bone script, where it depicted a kind of marking or division, evolving over millennia into its current standardized form.
