U+1FB16 "🬖" Block Sextant-45 Unicode Character

U+1FB16 "🬖" Block Sextant-45 is a symbol from the Symbols for Legacy Computing Supplementary block, representing a specific pattern used in early computer graphics, particularly in the Sextant system which employed a 2x3 grid of subcells. This character graphically fills the lower left two cells and the upper right two cells of that sixcell block, while leaving the remaining two positions empty, creating a checkerboardlike appearance. It was standardized in Unicode version 13.0 to preserve historical bitmap font and display methods from the 1970s and 1980s computing era.
