According to
http://www.haskell.org/ghc/docs/latest/html/users_guide/bugs-and-
infelicities.html#vs-Haskell-defn
GHC only accepts ISO-8859-1, but, when I try to compile this source file
in ISO-8859-1:
{{{
module Main where
main :: IO ()
main = do putStrLn "ano"
}}}
I obtain:
{{{
main.hs:3:21:
lexical error in string/character literal (UTF-8 decoding error)
}}}
And, if I save the source as UTF-8 it does compile, but, when running the
program, it prints "a".

Antonio Regidor Garcia
Comment:
This is a documentation bug. GHC currently accepts UTF-8 exclusively for
source text, and the run time system uses ISO-8859-1 exclusively for IO
(truncating the high bits of any characters).
