According to the [RFC 5280, section 4.2.1.6](https://tools.ietf.org/html/rfc5280#section-4.2.1.6): > ... > When the subjectAltName extension contains a domain name system > label, the domain name MUST be stored in the dNSName (an IA5String). > The name MUST be in the "preferred name syntax", as specified by > Section 3.5 of [RFC1034] and as modified by Section 2.1 of > [RFC1123]. Note that while uppercase and lowercase letters are > allowed in domain names, no significance is attached to the case. > ... And the [RFC 1034, section 3.5](https://tools.ietf.org/html/rfc1034#section-3.5): > ... > Note that while upper and lower case letters are allowed in domain > names, no significance is attached to the case. That is, two names with > the same spelling but different case are to be treated as if identical. > ... We should return the same TLS certificate for both `example.com` and `EXAMPLE.COM`. But the `autocert.Manager.GetCertificate` treats the two as totally different, it signs and returns two different TLS certificates. Moreover, now the `autocert.Manager.GetCertificate` and the `autocert.HostWhitelist` can only handle Punycode IDN. If the client sends a Unicode IDN to `autocert.Manager.GetCertificate` (cURL is doing this), the "Invalid character in DNS name" error will be triggered. This PR corrects these problems by converting the host of the TLS certificate to be obtained to Punycode via `idna.Lookup.ToASCII`.
