You could use a PUA code or the replacement character (U+FFFD) as an
escape code. I don't think this is possible in Linux or Unix in
general because I think POSIX mandates that '/' is reserved. It *may*
be possible in Windows if you're creating a custom file system and can
get away with requiring users to use \\?\ paths in this case. The
system parses the path up to the volume device, so that part cannot
use backslash. Beyond that, path parsing is up to file-system device
that manages the volume. If the volume is mounted in the object
namespace, then the whole path, including the device name, can use
forward slash, since that's just a normal name character to the object
manager. For example, you can create a device named "My/Device".
