I'm just guessing here but I expect that haskell-src and
haskell-src-exts are unicode aware but that you're using something like
readFile to read your UTF-8 .hs file. The readFile function (currently)
only reads text files in latin-1, not UTF-8. Try using the utf8-string
package and the System.IO.UTF8.readFile function instead.
