U+3378 "㍸" Square Dm Squared Unicode Character
Unicode Version 17.0
㍸
U+3378 "㍸" Square Dm Squared is a CJK Compatibility Ideograph that represents the square decimeter unit of area, abbreviated as "dm²". It is part of a set of precomposed square symbols in Unicode designed to represent common measurement units in East Asian text, particularly for compatibility with older character encoding standards. This character allows the unit to be displayed as a single, compact glyph, often used in contexts like technical documents, textbooks, or signage where clear representation of metric area measurements is needed. Its inclusion in Unicode ensures consistent rendering across different platforms and fonts, preserving the intended meaning without relying on separate characters or formatting tricks.
