Paths are encoded incorrectly when invoking GCC
Hello, I've been trying to get the ghc to compile a .hs file to binary. I get an error that seems to be caused during the C compilation phase from the special character ä in my user directory. When compiling I get this:
C:\Users\Erik Präntare>ghc C:\code\Haskell\test.hs
Linking C:\code\Haskell\test.exe ...
realgcc.exe: error: C:\Users\Erik Pr├ñntare\AppData\Local\Temp\ghc28912_0\ghc_1.
c: No such file or directory
realgcc.exe: fatal error: no input files
`gcc.exe' failed in phase `C Compiler'. (Exit code: 1)
Notice how it says Pr├ñntare instead of Präntare. The UTF-8 encoding for ä is 0xC3 0xA4 which, surprise surprise, corresponds to ├ñ in ASCII. Now, I managed to get around this by changing the tmpdir to my actual temporary directory, but as a new user of ghc it was very troublesome to find a solution. Maybe consider changing the default tmpdir, at least if special characters are encountered?
