OK but what if the international standards are wrong? Submit a bug to the standard. No, I don't know how to do it either, and I couldn't easily find it at unicode.org :(. I guess they don't want to make it easy. (Barbara, if you have any insights about this, plesae inform.)
I have no idea if it can be fixed or not, but there is no other way. We have to follow the standard even when it is wrong. It is even a *legal* requirement, if we want to say "we support Unicode" -- which seems pretty desirable to me. FWIW, fixing it at the polyglossia (or equivalent) level sounds like the only practical approach to me also. Sorry. Best, Karl
