file was UTF-8

Converted to UTF-8 without BOM, now works...

I'm not sure if that should already works on UTF8 with bom according this commit https://github.com/jaspervdj/stylish-haskell/commit/3598ec21fbd215350940ae064c38f0c756cef916

Also maybe this issue should be merged with https://github.com/jaspervdj/stylish-haskell/issues/3
