U+1BC25 "𛰥" Duployan Letter S with Dot Unicode Character

U+1BC25 "𛰥" Duployan Letter S with Dot is a character from the Duployan shorthand script, which was designed in the 19th century for efficient writing in various languages including French, English, and Indigenous languages of North America. This specific letter represents a modified version of the standard Duployan 'S', with a dot attached to indicate a distinct phonetic value, often used for a voiced or otherwise altered sibilant sound in transcription systems. The Duployan block was added to Unicode in version 7.0 in 2014 to support historical and contemporary use of the script, particularly in archival texts and language revitalization efforts.
