Wow. That's surprising. I do see the FreeBSD man pages say:
"The 4.4BSD extension of accepting arguments outside of the range of the
unsigned char type
in locales with large character sets is considered obsolete and may not be
supported in
future releases."
Now I think that might have been referring to >= 0xFF, but fair enough.
I've attached a gnulib patch to document for iscntrl at least.
It would be great if someone could test the other is*() classification
functions on macOS so that I might have a more complete documentation patch.
I've also attached an alternative patch for df (in your name).
Can you try that one?
thanks!
