Yes. It confuses users. And it is specifically confusing when people guess domain names (as they do) and it tries .com as the TLD -- and that is a pay per click, a site with various content that is not fun for the organisation that have a similar domain name in for example .SE.

You are correct in that it is a resolver issue and not application issue, but more and more applications include their own resolver, which then implement the same algorithm that was earlier in the normal resolver library.
For the user it does not really matter where the "change" is happening.

There are still many users that do not use Unicode as the charset of course. Of course, many charsets used do have direct 1:1 mappings to Unicode.
But yes, this goes away.
I just wanted to point out that these kind of "help" mechanisms that are different in different contexts already exists. It is not something new.
