U+03D5 "ϕ" Greek Phi Symbol is a typographic variant of the Greek letter phi, distinct from the more common circular phi (φ) and the capital Phi (Φ). In Unicode, it is formally named the "Greek Phi Symbol" and is used to represent the voiceless labiodental fricative sound in Greek, though in modern scholarly and mathematical contexts it often serves as a distinct symbol for the golden ratio, the empty set, or other scientific notations where a closed variant of phi is preferred. Visually, it resembles a circle with a vertical line through it, differentiating it from the open or looped form of the lowercase phi.
