U+6646 "晆" CJK Unified Ideograph-# Unicode Character

U+6646 "晆" CJK Unified Ideograph-# is a Chinese character (hanzi) primarily used in classical or literary contexts, though it is extremely rare in modern standard Chinese. Its meaning is generally associated with "a stretch of land," "a boundary," or "to separate," often referencing a division in terrain or a geographical limit. The character is composed of the radical 日 (sun or day) on the left, indicating a possible connection to time or brightness, and the phonetic component 圭 (gui, a jade tablet) on the right. In historical usage, it may appear in place names or old texts, but it is not included in modern common character lists, making it a specialized or obscure glyph within the CJK Unified Ideographs block.
