U+1BC7C "𛱼" Duployan Affix Attached Tangent Hook Unicode Character

U+1BC7C "𛱼" Duployan Affix Attached Tangent Hook is a specialized mark used within the Duployan shorthand system, a script designed for rapid phonetic writing of languages such as French, English, and German. This character functions as an affix, a small modifying stroke that attaches to the base of a Duployan sign to indicate a specific phonetic or grammatical alteration, such as marking a change in vowel sound or a shift in word context. The "attached tangent hook" distinguishes it from similar marks by its precise curved shape, which joins directly to a character’s stem to modify pronunciation without detaching, thus enabling efficient and compact notation in shorthand transcription.
