The Wikipedia has the following information about this codepoint:

The Duployan shorthand, or Duployan stenography (French: Sténographie Duployé), was created by Father Émile Duployé in 1860 for writing French. Since then, it has been expanded and adapted for writing English, German, Spanish, Romanian, Latin, Danish, and Chinook Jargon. The Duployan stenography is classified as a geometric, alphabetic stenography and is written left-to-right in connected stenographic style. The Duployan shorthands, including Chinook writing, Pernin's Universal Phonography, Perrault's English Shorthand, the Sloan-Duployan Modern Shorthand, and Romanian stenography, were included as a single script in version 7.0 of the Unicode Standard / ISO 10646
