Seems like the most devious "ascii-lookalike" ones probably have apparent ratios, but I don't know how this works for other scripts

Like, I imagine that there's potentially subtle swaps outside of Latin chars that's also dangerous? Not sure. Wouldn't want to ignore if so

You could have a "did you mean?/warning" type thing based on historical domains on the assumption intended domains are visited pre-phish but

I mean, scripts like Vietnamese use Latin bases with tiny squiggly diacritics. Not straightforward.

What homograph problem do Vietnamese diacritics pose?

Same as é and stuff, really, but harder to notice (ơ looks like a speck of dust).

If the problem being solved is users ignorant of Latin diacritics to the point of mentally filtering them out, that's hard to solve indeed.

Actually, it’s easy: require that names that differ only in diacritics belong to the same registrant. .fi at least used to require this.

Which, of course, requires TLD policy to put security ahead of greed, which is a problem given the MO of ICANN.

Hah. Agreed. This is the *correct* solution, but registrars aren't impling it, which is why browsers have stepped up (and should continue)

Yeah, our original policy was to whitelist registrars with good policies, but that ended up incompatible with other browsers (& no .com!)
