U+337A "㍺" Square Iu Unicode Character
Unicode Version 17.0
㍺
U+337A "㍺" Square Iu is a special CJK (Chinese, Japanese, and Korean) compatibility ideograph known as the "Square Iu" symbol, representing a unit of measurement for area in the Japanese metric system called "jou" or "tsubo." Originating from traditional Japanese usage, it corresponds to approximately 3.306 square meters and is often used in real estate and construction to denote the size of land or floor space. This character was included in Unicode as a precomposed square form to ensure compatibility with older text encoding standards, allowing it to be displayed as a single character rather than separate smaller text components.
