I still can't make any sense of what you've written so far in this
thread. Perhaps I'll stop trying.

As I said, I did apply the relevant set of options.
C++17 does not permit '$' in identifiers, and requires a diagnostic
for any program that attempts to use a '$' in an identifier.
Earlier editions of the standard do permit implementations to support
'$' in identifiers. gcc's lack of a diagnostic in conforming mode
"gcc -std=c++17 -Wpedantic" makes it non-conforming. If you agree
with that, I don't know what we're arguing about. If you don't,
I have yet to see an explanation.
I've also suggested that the committee probably did not intend to
make a significant change in this area.

I've never heard of any attempt to remove '$' from ASCII, which I
believe has not changed since 1967. Do you have a citation for that?
'$' is not in the source or execution basic character set, a decision
that was made a long time ago. Apparently '$' is not supported in
all versions of EBCDIC, or at least doesn't have a consistent code
(see the Wikipedia article). And there are no tokens in C or C++
that required $ (or @ or `, the only three printable ASCII characters
not in the C or C++ basic character set).

There is no "new ASCII". ASCII is a 7-bit character set. '¤' is part
of Unicode (and Latin-1). Unicode calls it "CURRENCY SIGN". It's not a
replacement for '$' (DOLLAR SIGN), which still exists in ASCII, Latin-1,
and Unicode. (DOLLAR SIGN is 0x24. CURRENCY SIGN is 0xA4.) If there's
a political issue, it's not one that interests me unless it's relevant
to C++.
