Implementations MUST make sure to use proper percent-encoding for URIs that can not be represented using unreserved URI characters. JSContact makes no recommendation how to display such URIs, but section "4.8.3 Internationalization and special characters" of the W3C URL Standard [W3C-URL] provides guidance for URLs found in context of a web browser.OK, but this section still needs to cover IDNs, right? Must the domain be in be punycode? That's what I assume, but I'm not sure you want that. Example: http://ああ.com
I don't think it needs to cover IDNs, as the valid syntax of a URI is defined in RFC 3986 section 3, for the http URI scheme specifically in RFC 9110 section 4.2. Neither specifications mention RFC 3429 (Punycode) as a reference.
I am wary of restating too many requirements in the JSContact RFC for which other RFCs are authorative: there's always the risk of getting it wrong. That especially applies to DNS: https://rfc-annotations.research.icann.org.
