Of course, it is in there. Logicians and mathematicians rarely, if
ever, use a backward epsilon, but they frequently use a reversed
"element of" symbol (derived from, but now quite separate from,
epsilon). The reversed "element of" is ∋ U+220B, a couple of slots along
from "element of" (∈ U+2208). Reversed forms of both epsilons are in,
as well.
