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).
That would only allow users of Hackage and Cabal to reliably exchange
their Haskell files. If we specify it in the report every user can
benefit.
I agree that Haskell files should be UTF-8, but I also agree that it is
only relevant for Hackage (and Cabal) and already enforced by ghc-6.12.
or higher.
The motivation for this proposal can only be that future cabal packages
will use more and more non-ASCII characters as is possible via
http://hackage.haskell.org/package/base-unicode-symbols-0.2.1.4 and
LANGUAGE pragma "UnicodeSyntax" (that happens to have no support for "\"
as lambda symbol - probably because lambda is a letter and no symbol!)
However, I think, these extra characters only make sense for corner
cases and should not be recommended for general purposes.
For nicer looking sources I would recommend special viewers or
post-processors (like haddock or hscolour) that translate certain ASCII
sequences to unicode points.
So my view is: Stick to ASCII and only if you must (not just for casual
reasons) use UTF-8.
