U+33C6 "㏆" Square C over Kg Unicode Character
Unicode Version 17.0
㏆
U+33C6 "㏆" Square C over Kg is a CJK Compatibility Ideograph that represents the unit "C over Kg," specifically denoting coulombs per kilogram, a derived SI unit of ionizing radiation exposure. This character is part of a set of compatibility characters originally encoded for use in East Asian text standards, where it served as a compact, square-shaped symbol for the complex unit in contexts like technical documentation and labeling. It is distinct from standard Unicode characters in that it was included primarily for round-trip conversion with older character sets, rather than for general modern use, and it highlights the effort to encode precomposed forms of common units or abbreviations in square format.
