U+A7A7 "ꞧ" Latin Small Letter R with Oblique Stroke Unicode Character

U+A7A7 "ꞧ" Latin Small Letter R with Oblique Stroke is a specialized typographic variant of the letter R, primarily used in historical and phonetic contexts, such as in certain 19th-century and early 20th-century transcriptions of Native American languages or in Latin orthographies where a distinct R sound needed differentiation. Its oblique stroke, which cuts diagonally across the bowl and stem of the letter, serves as a diacritic to indicate a modified pronunciation, often a fricative or devoiced version of the standard alveolar trill or tap. While relatively rare in modern computing, this character is included in the Unicode Standard's Latin Extended-D block to support scholarly work, linguistics, and the accurate digital representation of historical texts and minority language scripts.
