About the black square symbol
The character ■ is read as "black square" and is commonly spoken of as a solid square or filled square. It serves as a basic geometric symbol for indicating filled areas in diagrams, maps, and lists, often standing in for a bullet point or a checkbox mark. In technical contexts, it appears in flowcharts and schematic drawings to denote a process step or a filled state. The symbol also functions as a simple placeholder or separator in text, and its solid form distinguishes it from outlined or hollow square variants used in other notations.
