Interesting, and a quick sanity test with https://tools.ietf.org/html/rfc8187 works for me (= can see an € in 3.2.3), that should also cover all WikiMedia and MediaWiki projects linking to tools.ietf.org (not limited to RFCs, I-Ds are also often linked via tools.ietf.org). So now I can finally replace an ancient copy of vintage 2005 draft-hoffman-utf8-rfcs-01.txt by a more up to date RFC 8140 ;-) Skeptical, maybe the Unicode emoji for ;-) does not yet work everywhere, some folks including me are still using Windows 7 and not planning to upgrade before 2020.
