Wow this is an old attack. I wonder whether we could use computer vision to check for similar/confusing glyphs.

  In all the cases I've seen so far, the glyphs haven't just been similar, they've been the exact same glyphs, just in a different part of unicode. I think a lookup table would be enough. And then a rule that might be good to implement at registrars (please correct me if I'm missing a valid use case for this): if all the the unicode characters represent ASCII (or its 'duplicates'), reject the registration.

    I don't think that works, "cccp" could look identical in latin and cyrillic but represents 2 different acronyms.

      Oh, dang, good point.
