U+A7C5 "Ʂ" Latin Capital Letter S with Hook Unicode Character

U+A7C5 "Ʂ" Latin Capital Letter S with Hook is a historical Latin letter used primarily in early modern linguistic transcriptions of the Dene or Athabaskan languages of North America. Its design modifies a standard capital S by adding a small hook to the lower right stroke, a diacritic intended to denote a distinct sibilant or affricate sound, often a voiceless alveolar lateral fricative. This character was added to the Unicode Standard in 2022 as part of the Latin Extended D block to support scholarly and digital preservation of older orthographies and language documentation efforts. Its lowercase counterpart is U+A7C6 "Ᶎ", which similarly carries the hook below the letter.
