U+166B "ᙫ" Canadian Syllabics Carrier Ttsi Unicode Character

U+166B "ᙫ" Canadian Syllabics Carrier Ttsi is a letter from the Unified Canadian Aboriginal Syllabics block, specifically representing the Carrier language consonant sound "ttsi." This character is part of a writing system developed for Indigenous languages in Canada, and its form is derived from traditional syllabic scripts adapted to represent the phonetic inventory of Carrier, a Northern Athabaskan language spoken primarily in British Columbia. The symbol combines a distinct geometric shape with a small raised mark to indicate the specific voiceless affricate sound it denotes, and its use helps preserve and transmit the Carrier language in written documents and digital text.
