About this character

U+22AF (⊯) is NEGATED DOUBLE VERTICAL BAR DOUBLE RIGHT TURNSTILE, a mathematical symbol in the Mathematical Operators block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 1.1 (1993).

It is precomposed. Under NFD it decomposes into U+22AB ⊫ + U+0338 ◌̸, and NFC recombines that sequence into this single codepoint, so both spellings are canonically equivalent and should compare equal after normalization. See the normalization guide.
