A highly specialised typeface enabling digital encoding of Duployan shorthand, a 19th-century cursive stenographic script with limited modern use.
About
Noto Sans Duployan fulfils a narrow archival and scholarly function, providing Unicode-compliant rendering of a stenographic system once widely used in France and beyond. The two-weight offering is unusually generous for so rare a script, suggesting its utility in facsimile and archival reproduction contexts. Its primary audience is linguists, historians, and archivists working with historical shorthand documents.
Classification
Provides digital coverage for Duployan shorthand, a cursive stenographic system developed in the 19th century. Letterforms necessarily follow the simple, stroke-based geometry of the shorthand system itself.
