U+AB66 "ꭦ" Latin Small Letter Dz Digraph with Retroflex Hook Unicode Character

U+AB66 "ꭦ" Latin Small Letter Dz Digraph with Retroflex Hook is a specialized typographic symbol used in phonetic transcription, primarily within the context of the International Phonetic Alphabet (IPA) and certain orthographies for indigenous languages of the Americas. It represents a voiced retroflex affricate sound, similar to the sound of "dz" but produced with the tongue curled back against the palate, and its distinct hook attached to the bottom of the digraph visually indicates this retroflex articulation. This character is part of the Latin Extended-E block, which supports phonetic and other academic notation, and is typically employed by linguists and language revivalists to accurately document and preserve the distinct phonological features of languages such as those in the Iroquoian or Siouan families.
