German ß issue: The domain "Gießen.de" already exists.

[B4c4rd1]

TITLE:

German ß issue: The domain "Gießen.de" already exists.​

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:

Plesk Onyx Version 17.8.11 Update #48
Ubuntu 16.04​

PROBLEM DESCRIPTION:

If a domain with the name: "Giessen.de" (domain name is just a test) has already been created, you can not create another domain with the name: "Gießen.de".

Error Message: Incorrect name of the domain alias Gießen.de. The domain Gießen.de already exists.​

STEPS TO REPRODUCE:

Create a domain with the name: "Giessen.de" and add a alias with the name: "Giessen.de".​

ACTUAL RESULT:

Incorrect name of the domain alias Gießen.de. The domain Gießen.de already exists.​

EXPECTED RESULT:

The domain should be created and saved in IDNA 2008 format.

For example, at the file level: xn--gieen-nqa.de
Or in the database: xn--gieen-nqa.de

No Error!​

ANY ADDITIONAL INFORMATION:

I have read the following articles:

What is the problem with 'ß'
Plesk should support IDN names (IDNA 2008) on Linux, too. Domains with special characters can't be hosted.

But that is not a solution to the problem!​

YOUR EXPECTATIONS FROM PLESK SERVICE TEAM:

Confirm bug​

Ok, here comes a little workaround!

Create the domain as an ACE string: xn--gieen-nqa.de

There is a converter here: IDN-Web-Converter - DENIC eG

After the domain has been created, you must change the display name in Plesk's database:

1. "domain_aliases" change "displayName" from "xn--gieen-nqa.de" to "gießen.de"
2. "dns_zone" change "displayName" from "xn--gieen-nqa.de" to "gießen.de"

This method is only temporary. If the customer changes something here, it will come to errors. But maybe that will be so integrated by the Plesk team.

But you can also differentiate here. if a domain is already created "Giessen.de" then he should "Gießen.de" save it as an ACE string. If not, then he should save "Gießen.de" as "Giessen.de".

Or you create it correctly and always converts to an ACE string.
