U+AB67 "ꭧ" Latin Small Letter Ts Digraph with Retroflex Hook Unicode Character

U+AB67 "ꭧ" Latin Small Letter Ts Digraph with Retroflex Hook is a specialized phonetic letter used in certain linguistic transcriptions, particularly within the context of Uralic and other language documentation, to represent a retroflex affricate sound, similar to a combined 't' and 's' pronounced with the tongue curled back against the palate. This character is part of the Latin Extended-E block and was added to the Unicode Standard to support precise scholarly notation of retroflex consonants, which are common in languages such as Sanskrit, Mandarin Chinese, and various indigenous languages of India and Australia. The retroflex hook attached to the base of the digraph distinguishes this sound from its non-retroflex counterpart, allowing linguists and phonologists to accurately denote subtle phonetic distinctions in written form.
