but what you propose cannot be used in Windows at all! while current FilePath still works on Unix, with manual filenames en/decoding Now we got back on topic! :)

The FilePath datatype is OS-dependent and making it abstract should be at least a first step. If you got it from somewhere else where it is already encoded, then fine. If you need to construct it, then you need to use a smart constructor. If you need to show/print it, then you need to convert it to String. And so on.

It should solve most of problems I believe. But such change will break a lot of programs maybe most of them. How could one introduce such a change? One variant is to create new hierarchy and gradually deprecate old. I fail to see how it will brake programs. Current programs do not use Unicode because it is implemented incorrectly.
