The problem with .com really (Score 1)

IMHO it's the problem with .com domain policy – no top level domain should allow the use of different scripts/alphabets. Countries using cyrillic don't allow using cyrillic IDN domains under .ru and .bg for example, there are . and . for that. In the same way .com should allow ASCII only. Yes, there is theoretically homographs problem with top level domains as well, but it is realistically controllable.
