U+3318 "㌘" Square Guramu Unicode Character
Unicode Version 17.0
㌘
U+3318 "㌘" Square Guramu is a CJK compatibility ideograph that represents a square version of the Japanese katakana word "guramu," which is a transliteration of the English unit "gram." It is part of the CJK Compatibility block, designed for compatibility with older East Asian character sets used in vertical text or limited-width contexts, such as on receipts, labels, or typewriters, where a single character was needed to replace the two- character katakana sequence グ (gu) and ラム (ramu). Though modern Unicode recommends using standard characters for general text, this square form persists in legacy systems and certain specialized applications, signifying the metric unit of mass.
