Comment:

 I just noticed that my patch only works if `-XUnicodeSyntax` is passed on
 the command line, or set with `:set`. It does not work simply because you
 load a file with `LANGUAGE UnicodeSyntax`.

 Should it? Other pragmas (tested it with `RankNTypes`) in a loaded file
 also don’t affect what you enter at GHCi.

 Also, the pragma does not have an effect on the error message printed by
 the compiler in error messages from a file with `UnicodeSyntax` active.
 The `dynflag` passed to the pretty-printer seems to be a different one
 than used when type-checking.
