About this character

U+339C (㎜) is SQUARE MM, a symbol in the CJK Compatibility block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 1.1 (1993).

It is a squared (CJK compatibility) form of U+006D m + U+006D m (compatibility decomposition <square>). NFC and NFD leave it alone, but NFKC and NFKD replace it with U+006D m + U+006D m. Search engines, identifier checks and username systems that apply NFKC will treat the two as the same text.

Its East Asian Width is Wide, so terminals and monospaced layouts give it two columns.
