Note that this is why I personally think the binary API variants
*should* exist on Windows, just with the sense of the system encoding
flipped around.
That is, on *nix:
- underlying OS API uses bytes
- binary API just passes values straight through
- Unicode API uses the system encoding to encode Unicode names and
values to be passed to the OS API and to decode bytes names and values
received from the OS API
While on Windows:
- underlying OS API uses Unicode
- Unicode API just passes values straight through
- binary API uses the system encoding to decode bytes names and values
to be passed to the OS API and to encode Unicode names and values
received from the OS API
Cheers,
Nick.
