The problem is that there are packages there now with .cabal files assuming Latin-1. Stopping more of them from getting in is fine, but we need to display the ones that are there correctly. Hmm, after considering a few schemes it's probably simplest to introduce strict enforcement on upload and retroactively patch the existing Latin-1 packages to UTF.

That's not a valid UTF-8 sequence, but fromUTF is erroneously accepting it. It needs to tighten up to keep these errors out. Incidentally, a UTF decoder is also supposed to reject non-minimal encodings, e.g. a 3-byte encoding for a Char that can be encoded in 2 bytes. That's to force canonical encodings for security. _______________________________________________ cabal-devel mailing list [email protected] http://www.haskell.org/mailman/listinfo/cabal-devel
