Binding specifically to the first edition of ECMA-404 would resolve
that problem.  Binding to a specific edition doesn't work so well with
Unicode, but that is because Unicode is a special case: it expands its
coverage in successive editions to ever-larger portions of the world
of writing systems.  It would have been impossible to do the whole
thing at once, unlike even the largest ordinary technical standard.
ECMA-404 is not in that league.
