An uncommon non-IPA phonetic symbol for bilabial clicks is a turned b with hook, ⟨ɋ ⟩.

[1] In official IPA transcription, the click letter is combined with a ⟨k ɡ ŋ q ɢ ɴ⟩ via a tie bar, though ⟨k⟩ is frequently omitted.

The superscript IPA version is U+107B5 𐞵 MODIFIER LETTER BILABIAL CLICK.

[5] Similar graphemes consisting of a circled dot encoded by Unicode are: A symbol called a turned b with a tail was created and is used in older publications.

Still the deprecated IPA character is encoded at U+024B ɋ LATIN SMALL LETTER Q WITH HOOK TAIL.

Labial clicks only occur in the Tuu and Kx'a families of southern Africa, and in the Australian ritual language Damin.
