I agree that the current implementation is missing this, and more.
Have started to add tests based on Robins
Those includes & and / add + to that and we got most of it.
Also wants to have tests in place for base64 containing as you note +
and / for params post data
What would be interesting is examples of fields and situations where
these chars should not be encoded, for example is it an issue to
encode everything in username and password?
By moving most to "always" it should be possible to simplify the code
and still add functionality?
Unfortunately other things got in the way - so don't know when I can
continue that work.
