Basically, imagine a reversible transformation:

encode :: String -> [Word8] decode :: [Word8] -> String

this transformation is applied in the appropriate direction by the IO library to translate filesystem paths into FilePath and vice versa. No information is lost

I think that would be great if it were true, but it isn't: $ touch `printf '\x80'` $ touch `printf '\xEE\xBE\x80'` $ ghc -e 'System.Directory.getDirectoryContents "." >>= print' ["\61312",".","\61312",".."] Both of those filenames get encoded as \61312 (U+EF80). Thanks Ian
