U+2B15 "⬕" Square with Lower Left Diagonal Half Black Unicode Character
Unicode Version 17.0
⬕
U+2B15 "⬕" Square with Lower Left Diagonal Half Black is a geometric symbol that depicts a square with its lower left triangular half filled in black, leaving the upper right half white or empty. It belongs to the Miscellaneous Symbols and Arrows block and is often used in technical diagrams, mapping, or design contexts where a partial shading pattern is needed to represent a binary state, directional fill, or partitioned area. This character provides a clear visual cue for indicating a split or transitional zone, and its specific orientation of the diagonal line from the bottom left to the top right distinguishes it from similar half shaded square symbols.
