>From the GHC manual:

        GHC assumes that source files are ASCII or UTF-8 only, other
        encodings are not recognised. However, invalid UTF-8 sequences
        will be ignored in comments, so it is possible to use other
        encodings such as Latin-1, as long as the non-comment source
        code is ASCII only.

There is no option to have GHC assume a different encoding. You can use
something like iconv to convert .hs files from another encoding into
