No, please just ignore them and treat them like any other unassigned
character. Don't use them in plaintext files on POSIX systems, just as
you also don't use and do ignore the majority of the C0 and C1 control
characters. That is the most efficient and simple solution.
Do not try to anticipate the use of special characters that are not used
in practice today and that have no practical use in VT100-style terminal
communication.
