Comment (by judahj):
I don't think that'll fix it, unfortunately. For example, using non-
interactive ghc-6.11 we get similar issues:
{{{
$ ghc-stage2 --make fooα/Foo.hs
[1 of 1] Compiling Foo ( fooα/Foo.hs, fooα/Foo.o )
fooα/Foo.hs:3:0:
The type signature for `β' lacks an accompanying binding
}}}
As I understand it, the code path is:
- getArgs returns a !FilePath with the 'α' encoded as two separate 8-bit
Chars; the !FilePath is stored as-is in the !ModLocation.
- The status message calls showModMsg, which takes the !FilePath and
sticks it in the middle of a String message, still with two undecoded
bytes.
- That String is eventually printed to a text Handle, causing those two
bytes to be incorrectly re-encoded.
