JS allows unicode symbols too.

• yorwba 9y ago
  Most languages with first-class support for Unicode strings do. But usually they don't let you define custom operators. Haskell has this feature. While it is easily abused, it lets you write functions like: a ∈ [] = False a ∈ (x:xs) = a == x || a ∈ xs (some might consider this abuse)
