U+29BF "⦿" Circled Bullet Unicode Character

U+29BF "⦿" Circled Bullet is a typographic symbol belonging to the Miscellaneous Mathematical Symbols-B block, designed for technical and mathematical notation. It depicts a solid black dot enclosed within a circle, combining the visual weight of a bullet point with the framing of a circle to denote elements such as a defined set in set theory, a designated endpoint, or a point of interest in diagrams and lists. This character serves purposes distinct from its simpler counterparts, offering a more specific visual cue in contexts where clarity about a central, marked item is necessary, often used in mathematical proofs, technical documentation, or geometric illustrations.
