U+1FB04 "🬄" Block Sextant-13 Unicode Character

U+1FB04 "🬄" Block Sextant-13 is a symbol from the Symbols for Legacy Computing Supplementary block, specifically designed for representing a partial or segmented block in terminal and early computer graphics. It corresponds to one of the 64 possible sextant patterns, where a sextant divides a character cell into three rows and two columns, and the number 13 indicates a specific arrangement of filled and empty cells within that grid. This character was included to support the accurate reproduction of vintage computing displays, such as those from the Teletext or PLATO systems, which used such block elements to create low resolution graphical images or text effects.
