Comment (by RyanGlScott):

 If it's `cmd.exe`, then I think `setLocaleEncoding utf8` isn't quite
 enough to both (1) make the error go away, and (2) actually render all
 Unicode characters correctly. (It might fix (1), but (2) is another
 question.)

 For example, what is the output of:

 {{{#!hs
 main = do
     setLocaleEncoding utf8
     putStrLn "→"
 }}}
