But ByteStrings are neither ASCII nor 8-bit Latin text! [...] The intent of the not-yet-existing Unicode string is to represent text not bytes.

Right, so this will replace the .Char8 modules as well?

No, there is still a use-case for that, namely all these network protocols and file formats that mix binary and ASCII data.

After implementing an HTTP parser using ByteString in my web server I can say that the only thing you need from the .Char8 module is `pack' to be able to write byte literals. Matching bytes is better done using something like a `ByteSet' rather than the .Char8 functions as it gives better performance. -- Johan
