U+32CC "㋌" Square Hg Unicode Character
Unicode Version 17.0
㋌
U+32CC "㋌" Square Hg is a special CJK Compatibility Ideograph that represents the chemical symbol for mercury, Hg, enclosed within a square frame. It is part of the "Enclosed CJK Letters and Months" block and is typically used in East Asian text contexts, such as Japanese, where it may appear in place of the standard chemical notation for mercury, particularly in compatibility mappings or older encoding systems like Shift JIS. The character functions as a single typographic unit, preserving the square layout for consistent spacing and visual alignment in documents or interfaces that require enclosed symbols for chemical elements.
