That's why UTF-8 is suggested. UTF-8 has been developed to "fool" the

There is no NULL byte in any UTF-8 string except the one which
terminates it.

That is true. UTF-8 wouldn't cause any more problems than ascii already
does, such as some filesystems not allowing : and * in filenames among
other characters.

Yes, it uses unicode. And dos codepages in short ones. To prove this
take a vfat floppy and mount it. touch(1) a file on it that has some
non latin1 characters. Unmount the floppy then do dd if=/dev/fd0
of=/tmp/floppy bs=1024 count=512. While it's done take some hex
editor/viewer and seek the latin1-complaint part of the filename
in the floppy file (search for uppercase string). Righ above the short
filename you'll find multibyte long one.

You know this problem was "solved" over 20 years ago when it was
discovered that file-names could never be long enough. The solution
was a container-file which contained as much stuff as necessary to
identity the contents of the file that it was associated with. Using
this technique, the "real" file didn't need any ASCII identifiers. The
real file didn't show up in some directory program, just the contents
of the container-file. This same technique could be used for any
arbitrary file-identification including characters that haven't been
invented yet.
