0x2599

0x2599 refers to the Unicode code point U+2599, which is named QUADRANT UPPER RIGHT. It is part of the Block Elements range used for composing simple graphics in text environments. Along with the related quadrant characters U+2596 (QUADRANT LOWER LEFT), U+2597 (QUADRANT LOWER RIGHT), and U+2598 (QUADRANT UPPER LEFT), U+2599 represents a single quarter of a block in a 2x2 grid. These characters enable coarse shading or graphic construction in monospaced text.

The glyph for QUADRANT UPPER RIGHT depicts a small square in the upper-right corner of a four-cell block. Its appearance is highly font- and rendering-dependent; some fonts display a clean quarter-block, while others may render a more abstract or omitted glyph. Because of this variability, the character is primarily used in specialized text graphics, legacy terminal art, or situations where fine-grained bitmap-like blocks are needed without using full color.

In practical use, these quadrant characters are often employed to create progress indicators, simple charts, or decorative borders in environments that support Unicode but lack graphical UI capabilities. They are less common in modern user interfaces but remain part of the Unicode standard for text-based graphics compatibility across platforms.
