U+33A7 "㎧" Square M over S Unicode Character

U+33A7 "㎧" Square M over S is a precomposed CJK compatibility ideograph representing "meters per second," the standard SI unit for velocity or speed. It is designed for compatibility with East Asian text encodings where such units are sometimes displayed in a square format to save horizontal space or conform to stylistic conventions in scripts like Japanese. While it has a single defined meaning, its appearance may vary across fonts and platforms, and it is generally not recommended for modern digital use since the plain text "m/s" is more widely supported and accessible.
