    It might be difficult to capture the problem in its entirety by attempting
    to cutting down on homographs, for various reasons. So one idea that comes
    to my mind is to require that IDN's which uses non-ASCII characters must
    also register an additional name equivalent using ASCII characters only.
    Browsers would then be recommended to also display the ASCII equivalent, for
    names where this is available (and perhaps the opposite as well). (In fact,
    it would be good to recommend browsers to also display the IP address, as if
    it is funny, it can give hints of a spoof.) Then all sites can be reachable
    using an ASCII name, which I think is desirable from the point of view of
    international access.
