RFC 3986 support for query parameters

I noticed that RFC 3986-reserved characters (like :) aren't getting encoded in query parameters.

Here's an example from the tryingpan (ignore the 404, just trying to demonstrate that : doesn't get encoded as %3A):

Swagger does this out of the box:

I could intercept the requests and encode these characters "manually", but is there an existing way to support the RFC 3986 standard or are there plans to do so in the future?
