It looks like Cloudflare is corrupting the domain name. I have a domian that has non-ASCII characters (özcan-änderungsschneiderei). The domain is sent as: xn–zcan-nderungsschneiderei-ubc67b. Even subdomain such as qa is displayed on DNS dashboard as: xn–zcan-nderungsschneiderei-ubc67b
Is this a bug in Cloudflare DNS system?

Cloudflare is not corrupting your domain name; it’s encoded in Punycode, which is a standard representation for internationalized domain names (IDNs) with non-ASCII characters. The FAQ at the bottom of this page gives more details about IDN and Punycode:
Verisign IDN Conversion Tool To Convert Internationalized Domain Name Into Punycode - Verisign
I was able to see your qa subdomain, which is loading as expected. Your naked domain also is loading several files, and it’s showing a blank screen, which reflects an issue with your HTML/CSS/JS code.

Thanks for the reply. The reason qa subdomain works is because we setup our server to map the ACE domain name we receive from Cloudflare to the actual IDN domain name. Otherwise, it would not work. We have not published the production site, yet. That is the reason you do not see the home page.
I do not understand why Cloudflare needs to convert an IDN to ACE when communicating with a backend server. I can understand a DNS may need to store it internally in ACE, but why does it send ACE name and not IDN name to the backend server? After all, a visitor enters the IDN not ACE name. Also, in Cloudflare dashboard, the A record shows the domain in IDN. CNAME records are shown in ACE. If Cloudflare needs to store it locally in ACE, that’s their business. My question is why we have to see it in the Cloudflare dashboard in ACE format or receive it on our backend server in ACE format? Thanks for your assistance.
tbh I really don’t know. This is the kind of discretionary decision that only Cloudflare Team will be able to comment on.
