U+1BC4A "𛱊" Duployan Letter Ui Unicode Character

U+1BC4A "𛱊" Duployan Letter Ui is part of the Duployan shorthand script block, which was added to the Unicode Standard in version 7.0 to represent a system of phonetic shorthand developed by Émile Duployé in the 19th century. This specific character denotes the vowel sound represented by "ui" in the Duployan system, which was used primarily for writing French, English, and other languages in a simplified, rapid style. As a letter in this script, it functions as a distinct phonetic symbol rather than a diacritic, contributing to the compact representation of spoken language that made Duployan shorthand useful for transcription and note taking.
