Title: Don't Escape Tildes as per instructions in RFC 3986

If I'm reading this correctly, the tilde shouldn't be escaped:

>For consistency, percent-encoded octets in the ranges of ALPHA
>(%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D), period (%2E),
>underscore (%5F), or tilde (%7E) **should not be created by URI
>producers** and, when found in a URI, should be decoded to their
>corresponding unreserved characters by URI normalizers.
