Handle IO is also doing Unicode encoding/decoding, which iteratees bypass. Have you thought about how to incorporate encoding/decoding?
Yes; there will be a module Data.Enumerator.Text which contains locale-based IO, enumeratee-based encoding/decoding, and so forth. Since "iteratee" doesn't have any text-based IO, I figured it wasn't necessary for a first release; getting feedback on the basic soundness of the package was more important. Currently, I'm planning on the following type signatures for D.E.Text. 'enumHandle' will use Text's hGetLine, since there doesn't seem to be any text-based equivalent to ByteString's 'hGet'. -------------------------------------------------------------------------------- enumHandle :: Handle -> Enumerator SomeException Text IO b enumFile :: FilePath -> Enumerator SomeException Text IO b data Codec = Codec { codecName :: Text , codecEncode :: Text -> Either SomeException ByteString , codecDecode :: ByteString -> Either SomeException (Text, ByteString) } encode :: Codec -> Enumeratee SomeException Text ByteString m b decode :: Codec -> Enumeratee SomeException ByteString Text m b utf8 :: Codec utf16le :: Codec utf16be :: Codec utf32le :: Codec utf32be :: Codec ascii :: Codec iso8859_1 :: Codec --------------------------------------------------------------------------------
