Quadrant Upper Right

Quadrant Upper Right at U+259D is a block-drawing symbol that fills only the upper-right quarter of a character cell. It belongs to the Block Elements block, whose characters are used to build coarse graphics, shaded shapes, and text-mode layouts from fixed-width cells. Its main use is in terminal art, console interfaces, and monospaced diagrams where a designer needs quarter-cell precision without using images. Together with the other quadrant block characters, it can form simple icons, pixel-style curves, map tiles, progress indicators, or small charts inside plain text. It also appears in legacy-style user interfaces, roguelike games, bulletin-board-inspired graphics, and documentation that illustrates grid occupancy. In those settings, the exact visual result depends strongly on a monospaced font and consistent line spacing; in proportional fonts it may not align cleanly with neighboring block elements.
