U+1BC70 "𛱰" Duployan Affix Left Horizontal Secant Unicode Character

U+1BC70 "𛱰" Duployan Affix Left Horizontal Secant is a glyph from the Duployan shorthand script, an alternative writing system invented in the 19th century for rapid phonetic transcription of multiple languages, including English, French, and German. This specific character is classified as an affix, meaning it is a modifying mark that attaches to other Duployan characters to alter their pronunciation or meaning, and its name describes a leftward, horizontal, secant-shaped stroke. It belongs to the Duployan supplement block, a collection of lesser-used signs and affixes that extend the basic shorthand system, allowing for more precise representation of complex sounds. Although rarely encountered outside historical or academic contexts, this character is encoded in Unicode to preserve the full range of Duployan script for scholars, typographers, and enthusiasts of shorthand systems.
