Surely this shows the problem with the idea of a 'current encoding'
... You could be reading files from two remote servers each using
So you could have read and write raw [Word8] and read and write char,
readWithEncoder :: ([Word8] -> [Char]) -> IO [Char]
writeWithEncoder :: ([Char] -> [Word8]) -> [Char] -> IO ()
After all, how can you 'normalise' a filename to a standard encoding
if you don't have a function to do so. Infact if you encounter
a server with an encoding you have no converter for, you have no
choice but to treat it as raw bytes?
