U+66DF "曟" CJK Unified Ideograph-# Unicode Character

U+66DF "曟" CJK Unified Ideograph-# is a rare and ancient Chinese character that traditionally refers to a "morning star" or specifically the planet Venus when visible at dawn, and it is closely related to the character "晨" (chen, meaning morning or dawn). In classical Chinese texts, "曟" sometimes serves as a variant form of "晨" but carries a more poetic or astronomical nuance, emphasizing the time just before sunrise. This ideograph is composed of the radical "日" (sun, day) and a complex phonetic component, and it appears in historical dictionaries and literature, though it is seldom used in modern standard Chinese or Japanese, making it a notable but obscure entry in the Unicode CJK Unified Ideographs block.
