U+A731 "ꜱ" Latin Letter Small Capital S Unicode Character

U+A731 "ꜱ" Latin Letter Small Capital S is a typographic glyph from the Latin Extended-D block, designed as a small capital version of the letter S. It is primarily used in historical and phonetic contexts, particularly in medievalist orthographies and certain linguistic transcription systems where it represents a specific sound or serves as a distinct grapheme, often in studies of Old Norse or other early Germanic languages. Unlike the standard uppercase S, the small capital form is the same height as lowercase letters but retains the uppercase shape, allowing it to function in specialized alphabets without breaking the visual flow of text.
