There's a solution but it's awkward. We scandinavians use æøå but rarely do we use them in URIs. Like the electronics chain "Elkjøp" uses "elkjop.no" - this is coincidentally one of the few that has actually registered "elkjøp.no".

I have "kråke.re" myself but the DNS entry is really xn--krke-roa.re because international character DNS is an ugly, ugly hack.

Very interesting. Is it easy to type this special characters on your mobile?

That encoding is punycode, right?

I think all modern mobil keyboards show the regularly used chars depending on your language. So its very easy.

I think the punnycode encoding is just used for the domains, but not for the urls. The urls should be normal utf-8 encoding. Wonder why they made a difference at all.

i once tried the unicode urls and they are a pain in the a§§ because some browser (and mail clients) interpret them differently. Also some search engines and/or crawlers interpret them different (mostly they are double encoded). This in turn results in several "errors" that the developer then has to re- en/decode again server side to serve the correct content to url.

On the other side: Just "transliterate" a url is super simple and people all over the world can at least read the url (and probably memorise). For example: ä => ae => everybody in Germany knows how to read and interpret this.

SEO wise: No difference at all.

I believe because of Cyrillic URL spoofing from a about 10-15 years ago most people stay away from UNICODE urls. China's numeric URL's maybe so that tracking URL's are easier, but that's just a guess.
