Original Of (⊶) is the Mathematical Operators character at Unicode U+22B6 (ORIGINAL OF). In math and set theory it often marks the original (preimage) of a set under a function — the set of all inputs that map into a given set of outputs.
All of these produce the same glyph: ⊶. Prefer ⊶ in HTML source for clarity; use hex/decimal when generating entities, and CSS \22B6 only in content.
