    We discussed this issue during a break at the UTC last week, and I
    suggested pretty much the same thing. Rather than a true *homograph*
    mapping, what's needed is a *confusables folding*.

    If registration authorities could be convinced to use that to block all
    'look-alike' registrations, the playground for phishers would shrink

    Instead of having all variant spellings go to the same domain, it might be
    cleaner to simply have the incorrect variants fail.

    For ASCII, the confusables folding would fold 0 and O, 1 and l, as well as
    l and I, which can be confused in many fonts.

    For Latin / Greek / Cyrillic the set of confusables includes many true
    homographs, but there are many more for the other scripts.

    If someone is interested in creating a draft for such a folding, I'd be
    happy to maintain it as part of my set of draft foldings for future
    addition to UTS#30. (Speaking of the latter, once 4.1 is out the door, I'll
    have the time to release the approved version of that UTS).
