U+1BC64 "𛱤" Duployan Letter Nasal A Unicode Character

U+1BC64 "𛱤" Duployan Letter Nasal A is a component of the Duployan shorthand script, which was developed in the 19th century by French priest Émile Duployé for rapid writing in French, English, and other languages. This specific character represents a nasalized variant of the vowel "A," meaning it is pronounced with air flowing through both the mouth and the nose. It is part of a larger system of simplified phonetic symbols designed to capture speech efficiently, and it appears in the Unicode Standard under the Duployan block, which was added to support historical and linguistic documentation of shorthand systems.
