U+2920 "⤠" Rightwards Arrow from Bar to Black Diamond Unicode Character

U+2920 "⤠" Rightwards Arrow from Bar to Black Diamond is a specialized arrow symbol belonging to the Supplemental Arrows-B block, used in mathematical notation, logic, and technical diagrams to indicate a directional relationship ending at a solid black diamond. It combines a standard rightward arrow originating from a vertical bar with a filled diamond at its head, serving distinct purposes in fields like theoretical computer science, formal language theory, and geometry where it may denote a specific mapping, transformation, or a point of termination. Unlike simpler arrow characters, this symbol’s bar base suggests a fixed starting point or a set, while the black diamond emphasizes a precise, often terminal or intersection-based target. Its inclusion in Unicode ensures consistent digital representation across platforms for specialized technical and academic documents.
