ISO 15924 script code: Dupl

The Duployan script, devised by Émile Duployé, serves as a foundational system for shorthand writing, predominantly applied in French, English, and some indigenous American languages like Chinook Jargon. Its inception in the 19th century marked a revolution in stenography due to its phonetic representation, enabling swift transcription of spoken words for legal and legislative documentation. It’s supported on computers through Unicode, making it accessible on modern operating systems and applications.
