U+1FB03 "🬃" Block Sextant-3 Unicode Character

U+1FB03 "🬃" Block Sextant-3 is a graphic symbol belonging to the Symbols for Legacy Computing Supplement block, used to represent a specific pattern of three filled blocks within a sextant grid, a six cell rectangular frame typically employed in early computer graphics and terminal character sets. This particular code point corresponds to the pattern where the left half of the grid is fully filled and the single cell at the top right is also filled, leaving the remaining three cells in the lower left, middle right, and bottom right positions empty. It serves as a legacy computing glyph for recreating block based pixel art and text mode graphics from historical systems.
