Unicode Version 18.0

Source: Noto Sans CJK Source: Browser Default

U+542F "" CJK Unified Ideograph-# is a Chinese character (hanzi) that primarily means "to open," "to start," or "to enlighten," and it is also used in some Japanese, Korean, and Vietnamese contexts. Its structure combines the "mouth" radical (口) with a component suggesting opening or initiating, and it appears in common compounds like 开始 (kāishǐ, "to begin") or 启程 (qǐchéng, "to set out on a journey"). The character carries a sense of beginning or revealing, which is reflected in its use in words such as "启明" (Qiming, "morning star" or Enlightenment) and in modern contexts like technology, where it denotes system startup or activation. This ideograph is part of the CJK Unified Ideographs block in Unicode, which unifies similar characters from Chinese, Japanese, and Korean into a single encoding standard.
