I think this is wrong: UNIX version now appear which are in effect
processing UTF-8 without the BOM. Relatively minor changes are needed, as
these OS's already knows how t process 8-bit bytes.

So why do you keep it, when relatively minor changes to the standard would
make people happy, making all those discussions as well as all extra
programmer work that Unicode now requires go away?

If the question were only about XML-browsers and text editors, then the BOM
would probably be of little problem. But UNIX programs will not be executed
properly with it.
