url - Is there any way to avoid showing "xn--" for IDN domains?

Question

If I use a domain such as www.??ü.com, is there any way to avoid it being displayed as www.xn--4ca0bs.com in users’ browsers?

Domains such as www.xn--4ca0bs.com cause a lot of confusion with average internet users, I guess.

This is entirely up to the browser. In fact, IDNs are pretty much a browser-only technology. Domain names cannot contain non-ASCII characters, so the actual domain name is always the Punycode encoded xn--... form. It's up to the browser to prettify this, but many choose to not do so to avoid domain name spoofing using lookalike Unicode characters.
