Description

When creating a firewall alias and entering "www.bücher.ch" as the FQDN, pfsense gives an error stating:

"www.bücher.ch is not a valid host address, FQDN or alias."

This message is incorrect. www.bücher.ch is a valid FQDN.

Happily, entering the punycode representation (www.xn--bcher-kva.ch) results in everything working fine (alias can be created, rules using the alias work, ex: I can block that site).

I suggest that pfsense should accept Unicode characters in the FQDN textfield and internally convert them to punycode to pass down to pf or whatever other lower layers need it.

You can use URL/URL Table alias for IDN hostnames:
