U+2B1A "⬚" Dotted Square Unicode Character

U+2B1A "⬚" Dotted Square is a typographic symbol classified under the Miscellaneous Symbols and Arrows block, representing an empty or unfilled square composed of a dashed or dotted outline rather than a solid line. It is commonly used in text-based interfaces, mathematical notation, and form design to indicate a placeholder, a missing value, or a space to be filled, often as a visual cue in educational materials or digital checklists. The character's open, dotted structure distinguishes it from a solid square like U+25A0, and it is supported in most modern fonts and systems for general text display.
