Ẑ is a Latin script letter, the letter Z with a circumflex, used for transliteration of the Cyrillic letter Ѕ in ISO 9 family of transliteration standards, and rarely used in Pinyin as a shorthand of zh. It is also used in Poliespo for the sound /kts/, and in the Tsilhqotʼin language to represent pronounced as /link/.
In mathematics, ẑ often refers to the unit vector in the +Z direction.
