Might be easier to tie it in with the RFCs if it used macro names
borrowed from it.

Are there locales that aren't
https://en.wikipedia.org/wiki/Extended_ASCII ?  Yes, EBCDIC locales on
z/OS with Unix System Services installed is still POSIX-compatible AIUI
but definitely not ASCII, e.g. Fr_BE.IBM-1047 is
https://en.wikipedia.org/wiki/EBCDIC_1047.  Does the build farm have a
z/OS target?  :-)

A minor deviation is https://en.wikipedia.org/wiki/ISO/IEC_6937 which
replaces `$' with `¤', U+00A4, currency sign, as if other fiat
currencies of note exist in the world.

Cheers, Ralph.
