He's not trying to report a bug; he's just complaining about base's long-known lack of support for non-latin1 encodings. (IIUC)

Which is a bug. Base needs to support (in an /obvious/ way) (1) direct I/O of octets (bytes), with no character interpretation set

Data.ByteString

And does this work for Non-GHC yet? And when does it get added to Haskell' and guaranteed to work?

(2) I/O of text in UTF-8.

not in base, but see utf8-string on hackage.haskell.org.

Yes, this a decent layering of (2), on top of (1), for GHC only, depending on it to reading the bytes, and interpreting them as Latin-1.

...

(1) can currently be done, but it's not at all clear how to do so, or once you have figured out how to do so, why it works.

(This may be a bit out of date, but seeing this brought up again, I think not.)

I think its a little out of date, given Data.ByteString and utf8-string?

It's not obvious that ByteString is the place to look for I/O, so it's not yet good enough. It should be as easy to use as character I/O, and as easy to find. -- Aaron Denney -><-
