Unicode Version 18.0
Source: Browser Default
U+339C "㎜" Square Mm is a precomposed CJK compatibility ideograph that represents the square millimeter unit of area measurement, commonly used in technical and scientific contexts. It was included in Unicode primarily for compatibility with older East Asian character encoding standards, such as those used in Japanese industrial and typographic systems, where such squared unit symbols are frequently employed in technical documentation and specifications. This character occupies a single code point and is distinct from sequences of individual characters like "mm" or "mm²", as it is designed to display as a single, compact glyph for precision in specialized text environments.
