In GHC 7.0.3 / Mac OS X when trying to:

I get:

The string I am trying to write can also be seen here:

\55357 and \56384 would be surrogates D83D and DC40 for use in UTF-16
only. Haskell's Char is not a UTF-16 code unit (unlike early versions of
Java and probably current ones). GHC is correct in rejecting them.
Haskell's Char is a Unicode character directly. If you want the
character U+1F440 "EYES", write \128064 directly (or \x1f440, or \x1F440).
Use http://www.unicode.org/charts/ to find out what you are getting
into. You can enter a hexadecimal number or choose a category.
