U+25AD "▭" White Rectangle Unicode Character

U+25AD "▭" White Rectangle is a geometric symbol representing an outlined or hollow rectangular shape, typically appearing as a thin, unfilled border rather than a solid box. It belongs to the Geometric Shapes block of the Unicode standard, which includes a variety of basic figures used in mathematics, typography, and user interface design. In digital and printed contexts, this character can serve as a placeholder, a visual marker, or an element for diagrams and tables, often contrasting with its filled counterpart, the Black Rectangle (U+25AC). Its simple and neutral design makes it useful for creating grids, bounding boxes, or abstract representations in text-based environments.
