[FFmpeg-devel] file protocol with Unicode support

That is exactly what I said, but I was more specific: the way Linux provides
Unicode support is that it does not: file names are sequences of bytes, not
characters. Interpreting the bytes as characters is left to applications
that directly communicate with the outside world.

And in doing so, they failed utterly since they made their wchar_t 16 bits,
which is not large enough to handle Unicode.

I'd say that if someone's "codepage" is not able to encode the file names he
has on his devices, he asked for it.

But you came up with a satisfactory solution in the other mail anyway.
