Improve support for IDN


Cloudflare’s support for IDN is not complete.


  • When adding custom domains to Cloudflare Pages, IDNs are not considered valid domains.
  • When adding a page rule, the destination address of the forwarding URL cannot directly fill in the IDN.
  • Emails sent by Cloudflare show Punycode instead of IDN.
  • Cloudflare Registrar does not support IDN.

Hopefully Cloudflare will gradually improve its support for IDN.

Best Regards,

Yes I have this issue with Cloudflare a lot too. At least they should automatically convert typed IDN to punycoded.

This could easily be fixed in many parts if the Cloudflare website with some JS client side enhancements in the meantime. The user experience for IDNs is quite poor at the moment.
