[Haskell-cafe] Has character changed in GHC 6.8?

I vaguely remember that in GHC 6.6 code like this
length $ map ord "a string"
being able able to generate a different answer than
length "a string"
At the time I thought that the encoding (in my case UTF-8) was “leaking
through”. After switching to GHC 6.8 the behaviour seems to have
changed, and mapping 'ord' on a string results in a list of ints
representing the Unicode code point rather than the encoding:
> map ord "åäö"
Is this the case, or is there something strange going on with character
I was hoping that this would mean that 'chr . ord' would basically be a
no-op, but no such luck:
> chr . ord $ 'å'
What would I have to do to get an 'å' from '229'?

What if I don't want to obey the laws? Do they throw me in jail with
the other bad monads?
