Hi, One of my colleagues asked about using Unicode symbols in Haskell operators and I initially thought that this was supported. However, the code at the bottom of this message doesn't parse, reporting a lexical error on basically all of the funny characters of the form: Main.hs:1:5: error: lexical error at character '\65288' Character 65288 (0xff08) is punctuation [Ps] which I understand to mean it counts as a uniSymbol in the lexical structure described in the Haskell Report. https://www.haskell.org/onlinereport/haskell2010/haskellch2.html#x7-160002.2 Should this work? Not that I really want this specific example to work, but I'm interested to know why. Many thanks, David $ cat app/Main.hs foo （›’-’）› bar = False foo ‹（’-’‹） bar = False foo ∧（’-’）∧ bar = False foo ∨（’-’）∨ bar = False $ cat app/Main.hs | base64 # try and avoid mangling in email Zm9vIO+8iOKAuuKAmS3igJnvvInigLogYmFyID0gRmFsc2UKZm9vIOKAue+8iOKAmS3igJnigLnv vIkgYmFyID0gRmFsc2UKZm9vIOKIp++8iOKAmS3igJnvvIniiKcgYmFyID0gRmFsc2UKZm9vIOKI qO+8iOKAmS3igJnvvIniiKggYmFyID0gRmFsc2UK
