U+1FB1B "🬛" Block Sextant-1345 Unicode Character

U+1FB1B "🬛" Block Sextant-1345 is a member of the Symbols for Legacy Computing supplement block, which encodes graphic characters used in historical computer and teletext systems. This specific character represents a block sextant, a geometric shape that divides a square into six parts, with the particular pattern 1-3-4-5 indicating which of the six triangular or trapezoidal subsegments are filled. It was added to the Unicode Standard to support the accurate representation of legacy text and graphics, particularly from 1980s and 1990s home computers and videotex systems that relied on such block elements for low resolution visual rendering.
