U+2B57 "⭗" Heavy Circle with Circle Inside is a typographic symbol that features a thick, heavy outer circle with a smaller circle embedded concentrically within it, giving it a bold, target-like appearance. It belongs to the Miscellaneous Symbols and Arrows block, where it serves as a decorative or diagrammatic element, often used in technical documentation, user interface design, or visual notation to indicate a focus point, a button state, or a specific process step.
