TILT, game over. I think that was never correct, compare
RFC 2396 section 2.4.3 "excluded US-ASCII Charactes".
Simplified, after an <authority>, if you use this, you
have to match a path/query/fragment structure, even if
you don't need any path/query/fragment. In the "path"
you can use any <pchar> as is. Notably not "/" (unless
it separates path-segments), not "?" (starts a <query>),
not "#" (starts a <fragment>). As soon as you are in
the <query> you can also use "/" and "?" as is, but not
"#" (still starts a <fragment>).
Some VCHARs are *never* okay, e.g., "<", ">", "{", "}",
and '"'. Wherever you are in the URL, they have to be
percent-encoded. Ditto "[" and "]" unless they delimit
IPv6- or IPvFuture literals in the <authority>.
IIRC "#" is also never allowed as is, unless it starts
a <fragment>. If you want to use tel: maybe start with
a 3966bis (?)
