Plesk should support IDN names (IDNA 2008) on Linux, too. Domains with special characters can't be hosted.
You should really allow current IDN domain names, esp. with characters like "ß", which isn't just "ss".
IDNA 2008 is supported in Plesk for Linux and you can host all special characters including “ß”. The only thing you cannot do – is to host “ss” and “ß” versions of domain simultaneously.
Please see this problem fully explained from our perspective here http://devblog.plesk.com/2014/12/what-is-the-problem-with-s/
Yes, DNS zone in Plesk will formed to match browser expectation.
Let me show by example:
http://faß.de will be treated by every browser as fass.de (according to IDNA 2003 or transitional IDNA 2008 aka TR46)
So for faß.de Plesk follows the same rule (so called transitional IDNA 2008 aka TR46) and forms DNS zone as if for fass.de
Now, once Plesk would attempt to form true non-transitional IDNA 2008 DNS zone (which would be xn--fa-hia.de) we will immediately fail into situation of browsers requesting "fass.de" from DNS servers and Plesk DNS only knowing "xn--fa-hia.de"). So now if you DNS test for correct IDNA 2008 zone - results are great, "xn--fa-hia.de" zone is formed. But each and every site visitor will get "domain not found" error.
So what is preffered result:
- DNS test for IDNA 2008 passes, but site visitors fail ("domain not found" in browser)
- OR DNS test for IDNA 2008 fails, but visitors come to site
thanks for your fast reply. This isn't just a browser problem though. I can't even setup a correct DNS zone.
