It's worse than that because for some latin based IDNs there can be numerous permutations, as in way more than two, of similar looking names that can be formed using accents. What a mess!
And a potential UDRP minefield.
There's money to be for sure with latin based IDNs, but in my view, investing in / developing them is very risky unless one also owns the non-latin non-accented version too; ie. avião.com
and aviao.com.
