U+25D8 "◘" Inverse Bullet Unicode Character

U+25D8 "◘" Inverse Bullet is a typographic symbol that represents a small, solid square shape with a hollow, or inverse, appearance, typically rendered in black with a white circular indent or as a white square on a black background. It belongs to the Geometric Shapes Unicode block and is used in data processing, old text-based interfaces, and some notational systems to indicate a binary state, a placeholder, or a distinct visual marker separate from the standard filled or hollow bullet points. Its design and usage stem from early computing and character encoding standards, where it served as a visual indicator in memory maps, cursor representations, or menu selections in legacy systems.
