[math-fun] Good set-theory symbols

Anyone know of a good Unicode set-union symbol? I've been using ∩ for intersection and ∪ for union in Word documents. I like the former but I find the latter too elongated. I've checked a few places on the web but can't seem to find an upside-down ∩ . (Is there something that does for Unicode what detexify does for tex?) Thanks, Jim Propp
