 To reproduce, check out a fresh copy of GHC and `export LC_ALL=C` before
 going through the steps to build it.

 Commit 96adf0e99 introduced non-ASCII (UTF-8) text into
 `compiler/parser/Parser.y.pp` in a string literal.  `happy` tries to read
 this file in the encoding corresponding to the system locale.  Probably
 `happy` ought to declare that all its input files are UTF-8, like GHC
 does, but it currently doesn't, so it seems best to just ensure that
 `Parser.y.pp` is pure ASCII.

 Patch attached.
