U+1FB9B "🮛" Left and Right Triangular Half Block Unicode Character

U+1FB9B "🮛" Left and Right Triangular Half Block is a typographic symbol from the Symbols for Legacy Computing supplement, used to represent a graphic block that features a left-pointing triangle adjacent to a right-pointing triangle, together filling a single character cell. It was added in Unicode version 13.0 in 2020 to aid in the accurate rendering of retro computer graphics, terminal interfaces, and pixel art where such shapes replace standard square blocks for creating more nuanced visual patterns. This character is part of a larger set designed to preserve and reproduce the character-based graphics of early computing systems, allowing for the construction of mosaics or diagrams with slanted edges rather than purely rectilinear forms.
