Let's call this one proposal 0:
* Haskell98 file IO should always use UTF-8. * Haskell98 IO to terminals should use the current locale encoding.
1. all text I/O is in the locale encoding (what C and Hugs do)
2. stdin/stdout/stderr and terminals are always in the locale encoding, everything else is UTF-8
3. everything is UTF-8
3 is my favourite. It means that if I run ./foo and I want to see exactly what the output was, I can run ./foo | hexdump -C and get something consistent with the first run. 0 breaks the above. 1 means that if you and I both generate a file we don't necessarily get the same file. 2 I don't like for your "prog in" vs "prog < in" reason, and likewise "prog -o out" vs "prog > out". I think it's important that we have some way of sending/getting binary stuff to/from std*, though (and we need to make sure it plays nicely with buffering). Thanks Ian
