Having thought this over a bit more, I don't think it's a good idea.
Allowed? Allowed for what?
What does it achieve? Nothing, as far as I can see. Authors will still
be able to write their Haskell code in any encoding they like. And any
compiler can have a front-end script with an option to specify the
encoding used by source files, which simply uses iconv on the fly to
translate.
I think the real place to mandate UTF-8 would be for Hackage. That's
where it matters (an alternative design would be to add an encoding
field in the .cabal file, but I don't think this has much merit).
