U+1FB31 "🬱" Block Sextant-356 Unicode Character

U+1FB31 "🬱" Block Sextant-356 is a visual symbol from the Symbols for Legacy Computing block, designed to represent a specific pattern within a sextant grid, which divides a square into six triangular sections. This particular character, numbered 356, fills three of those triangular cells to form a distinct geometric shape, historically used in early computer graphics and terminal displays to create coarse bitmap images or text-based diagrams. Its inclusion in the Unicode standard helps preserve and digitally render these retro computing graphics, ensuring compatibility with older systems and documentation.
