Why? For destinations the data type is "byte string"
that covers much more encodings than you can think of.

But the tools inbetween apply restrictions (plain TeX,
LaTeX, XeTeX, xdvipdfmx, ...).

And for example, XeTeX adds the restriction that
arbitrary 8-bit bytes cannot be written. A severe
restriction when dealing with binary formats and
arbitrary data.
