Yes, please.

I’ve been using UTF-8 in comments in mksh for a while, and it
hasn’t broken on Minix, Plan 9, DEC ULTRIX, 4.4BSD on Windows,
Dell UNIX (bare SVR4), Haiku, Syllable OS, and a plethora of
other old, weird, and other systems. Even Xenix works… and an
EBCDIC system as well.

They just interpret it as pertaining to whatever the local
codepage is, and the EBCDIC system converted it as-if-it-were
“extended ASCII”, but it hasn’t broken anything.

IOW, I haven’t seen a nōn-8bit-clean C compiler yet. Nor sh.
