Pardon me if I'm misunderstanding withCString, but my understanding of unix
paths is that they are to be treated as strings of bytes. That is, unlike
windows, they do not have an encoding predefined. Furthermore, you could
have two filepaths in the same directory with different encodings due to
In this case, what would be the correct way of handling the paths?
Converting to a Haskell String would require knowing the encoding, right?
My reasoning is that Haskell Char type is meant to correspond to code
points so putting them into a string means you have to know their code point
which is different from their (multi-)byte value right?
Perhaps I have some details wrong? If so, please clarify.
