Using internationalised custom domain names on Azure Static Web Apps

Stephen Ponsford 0

Team is working with a number of clients who wish to use internationalised domain names, example [www.mācronincluded.com].

When adding custom domains, both the original and Punycode versions fail to validate.

CName redirect also doesn't work due to missing SSL?

Any solutions or workarounds?

Hi @Stephen Ponsford
Thanks for the question and using MS Q&A platform.

Azure App Service does not support Internationalized Domain Names (IDNs) natively. However, you can use Punycode to represent Unicode characters in ASCII characters.

Regarding the validation issue, it is possible that the validation is failing because the domain name is not in the correct format. Please make sure that you are entering the domain name in the correct format, for example, "xn--www-mcronincluded-6tb.com" instead of www.mācronincluded.com.

Ensure Proper SSL Certificate Coverage

Multi-Domain Certificates: If you are using CNAME records for multiple subdomains or domains, ensure that your SSL certificate covers all necessary domains, including both the IDN and its Punycode equivalent. This may require obtaining a multi-domain or wildcard SSL certificate that includes all relevant domain variations.

CNAME Setup: Verify that your CNAME records are correctly configured in your DNS settings. The CNAME should point to the appropriate target domain, and there should be no conflicting records that could cause resolution issues.

Redirects: If using CNAMEs leads to issues with content delivery (e.g., showing default pages), consider implementing HTTP redirects on your server to ensure users are directed to the correct content based on their requested URL.

I hope this information is helpful.

We have also tried a few times with the punycode version, let me get the team to get some screenshots of the puny code being used.
