U+330F "㌏" Square Ganma Unicode Character

U+330F "㌏" Square Ganma is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents a squared katakana rendering of the word "ganma," which is the Japanese pronunciation of the Greek letter "gamma." It is part of the "CJK Compatibility" block, a set of characters originally included for compatibility with older Japanese character encodings like Shift JIS, where such squared forms were used as shorthand for specific terms. In practical use, this character appears in contexts where "gamma" is abbreviated, such as in scientific, mathematical, or technical notation, particularly in Japanese typography where a square encloses the katakana characters "ガ" (ga), "ン" (n), and "マ" (ma) to form a compact symbol.
