U+24FF "⓿" Negative Circled Digit Zero Unicode Character
Unicode Version 17.0
⓿
U+24FF "⓿" Negative Circled Digit Zero is a typographic symbol that represents the number zero enclosed within a circle, but with the distinctive feature of a negative or inverted style, often appearing as a white digit on a dark circular background. It belongs to the Enclosed Alphanumerics block and is used in specialized contexts such as notating positions on game boards, labeling diagrams, or creating ordered lists where a rounded, visually distinct zero is needed to contrast with positive numbers. While not a common everyday character, it serves a functional role in design and publishing systems that require clear, compact numeric annotation within a circular boundary.
