The question is perhaps then if that new option should rather be A) "don't
URL encode host names" or B) "don't URL encode host names that are valid IDN
names".
Making it A) is way simpler and make a more predictable behavior.
I realize I'm now down in the weeds and I probably lost all of your interest
by now but it struck me I should probably reverse the option:
Stick to returning the name *un*-encoded by default in URLs and introduce a
new option that percents-encode the host name when the URL is retrieved.
This, to maintain the existing behavior to a larger extent. Parsing a URL with
an IDN name and then again extracting the URL will then work identically as
before, with the addition that it will also decode percent-encoded parts of
the host name.
I'll work on this in the PR.
