I'm not an RFC wizard, but I've seen this come up before and it's an
excellent question.
$ perl -MMojo::Parameters -E 'say Mojo::Parameters->new(var=>"a b")'
var=a+b
$ perl -MMojo::Parameters -E 'say Mojo::Parameters->new("a b")->to_string'
a%20b
This struck me as interesting, so I dug into RFC3986
<http://tools.ietf.org/html/rfc3986> (as referenced by Mojo::Parameters
<https://mojolicious.org/perldoc/Mojo/Parameters>) and I see this from section
3.4 <https://tools.ietf.org/html/rfc3986#section-3.4>:
However, as query components are often used to carry identifying
information in the form of "key=value" pairs and one frequently used value
is a reference to another URI, *it is sometimes better for usability to
avoid percent- encoding those characters*.
So, given that bold, I take it to mean that Mojo::Parameters decided to go
for what's "sometimes better". :)
