Thanks for the report.  GHC is erroneously passing some of the non-ASCII
characters used in identifiers in the module through unmodified into the
intermediate C output, when it should be encoding them using ASCII
characters only.

As a workaround, use the native code generator (-O -fasm, or just turn
off -O).
