All platforms.

Domain names in Unicode and in ASCII, by Unicode IDNA Compatibility Processing (UTS #46) of Unicode 18.0.0, revision 36.

The options are those of UTS #46, and default-options holds the ones that the URL Standard uses for the domain of a URL. NFC comes from the platform. A domain is an error rather than a guess when it has a new code point that NFC doesn't leave alone and the platform doesn't know.

default-optionsclj/s

The options that the URL Standard uses for the domain of a URL, both in ToASCII when it isn't strict and in ToUnicode:

  • :check-hyphens?, true to refuse a hyphen at the start or the end of a label, or in its third and fourth place
  • :check-bidi?, true to check right-to-left labels by the rules of RFC 5893
  • :check-joiners?, true to check U+200C and U+200D by the CONTEXTJ rules of RFC 5892
  • :use-std3-ascii-rules?, true to allow only a-z, 0-9 and - of ASCII
  • :transitional?, true for the deprecated mapping of ß, ς, U+200C and U+200D
  • :verify-dns-length?, true to check the lengths that DNS allows, with no empty label
  • :ignore-invalid-punycode?, true to keep a label of xn-- that doesn't decode as it is

(process domain)
(process domain opts)

The Unicode domain mapped, normalized and converted by the processing steps of UTS #46 with opts, as a map of the :domain and whether an :error? was recorded. The opts override default-options.

The Unicode `domain` mapped, normalized and converted by the processing
steps of UTS #46 with `opts`, as a map of the :domain and whether an
