U+1FB6F "🭯" Lower Triangular One Quarter Block Unicode Character

U+1FB6F "🭯" Lower Triangular One Quarter Block is a graphic symbol in the Symbols for Legacy Computing supplement block, representing a solid triangular shape occupying the lower right quadrant of a character cell. It was added to Unicode in version 13.0 in 2020 to aid in the accurate digital reproduction of vintage computer text and graphics, particularly from early monochrome displays that used block elements for pixelated imagery. This character, along with other quarter block variants, allows for finer control over shading and geometric shapes than the simpler half block characters, making it useful for emulating retro pixel art or terminal interfaces.
