U+9578 "镸" CJK Unified Ideograph-# Unicode Character

U+9578 "镸" CJK Unified Ideograph-# is a rarely used Chinese character that represents the concept of "long" or "length," functioning as a variant form of the more common character 長 (cháng), which also denotes length or duration. In traditional Chinese and Japanese kanji usage, 镸 appears primarily in historical or classical texts, often as an alternate written form. Its structure combines the radical for "long" (镸, a variation of 長) with additional components, though in modern contexts it has largely been supplanted by the standard 長 character in everyday writing. The Unicode encoding ensures that this archaic glyph remains accessible for digital representation in historical, linguistic, and calligraphic applications.
