U+31F2 "ㇲ" Katakana Letter Small Su Unicode Character

U+31F2 "ㇲ" Katakana Letter Small Su is a relatively rare typographic variant used in the Japanese writing system, specifically within the katakana syllabary, where it denotes a smaller version of the standard character "ス" (su). This smaller form primarily appears in phonetic annotations, such as in furigana or mixed-script texts, to indicate a shortened or devoiced pronunciation of the "su" sound, often in contexts like notation for the Ainu language or in precise linguistic transcription, but it is not employed in standard modern Japanese orthography.
