GHC does not support Unicode mathematical functions

Summary

GHC seems to be anchored in the late 60's. If it purports to support Unicode, why do the math functions ≤, ≥, ≠, ∧, and ∨ give errors? You need to get away from ASCII and start supporting Unicode. Or is Haskell just syntactic sugar for C like Python?

Steps to reproduce

5 ≤ 5 7 ≥ 3 0 ≠ 0 True ∧ True False ∨ True

Expected behavior

Return the value of the function. :version

Environment

GHC version used: The Glorious Glasgow Haskell Compilation System, version 8.6.5

Optional:

Operating System: Ubuntu MATE 20.04.3
System Architecture: AMD x64
