There should be one character ("0") that matches as many characters as
collate equal to the character "0", as per the POSIX quote in my previous
message.

Sure.

That should fix the problem without forcing applications to attempt to
impose a total ordering even when strcoll/wcscoll returns 0.

Yes, so the locale definition files imposing a total ordering will be a
clear improvement.

There are codepoints that correspond to characters in one locale but don't
map to a valid character in another.
