GHC is now expected source files to be UTF-8 only.  I really did this as 
an experiment to see if anyone complained, because it will be more work 
to implement other encodings.  You're the second person to notice this. 
  So - do you need Latin-1, or could you use UTF-8?

If you're using emacs, it's pretty easy to default to UTF-8 for haskell 
source files, BTW.  Just add this to your .emacs:

(modify-coding-system-alist 'file "\\.l?hs\\'" 'utf-8)
