And it gets even more fun when browsers such as firefox implemented this, then decided no we won't do it and removed the feature -- now there's no way to access your router web interface over link-local address...

(rationale being that whatwg said no: https://github.com/whatwg/url/issues/392 ; firefox bug https://bugzilla.mozilla.org/show_bug.cgi?id=700999 )

The "solution" is to use a proxy such as https://github.com/twisteroidambassador/prettysocks/tree/ipv... which incidentally encode the % as a `s` and handle special URLs like this http://fe80--1ff-fe23-4567-890as3.ipv6-literal.net for you through the socks dns resolution feature... I've never found anything else that works recently -_-
