U+1CEA7 "𜺧" Upper Half Left One Quarter Block Unicode Character

U+1CEA7 "𜺧" Upper Half Left One Quarter Block is a symbol in the Symbols for Legacy Computing Supplement block, specifically designed to represent a filled block that occupies the upper left quarter of a standard character cell. This character is part of a larger set of block elements used in historical computing interfaces for text mode graphics, where such partial blocks allowed for more detailed pixel-level representations on monochrome or limited-color displays. By only filling the top-left portion of the cell, it provides a precise means for constructing grid-based visual patterns or characters for terminal art, early video games, and other systems that relied on character matrices for rendering simple graphics.
