About this character

U+2209 (∉) is NOT AN ELEMENT OF, 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+2208 ∈ + 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.

It is a mirrored character: in right-to-left text it is displayed as its mirror image, which matches U+220C ∌.
