Hi all!

I have a question, the package URL implements the RFC 3986 although if I read it correctly in section 2.2 it says about reserved chars:

      reserved    = gen-delims / sub-delims

      gen-delims  = ":" / "/" / "?" / "#" / "[" / "]" / "@"

      sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
                  / "*" / "+" / "," / ";" / "="

However, checking the source of the current go implementation

I don't see the '(' and ')' part of reserved.

So this is causing some problems when I do http.Get() with urls that contains parens because they get escaped from http://example.com/fit-in/236x345/filters:quality(90):fill(ffffff) into http://example.com/fit-in/236x345/filters:quality%2890%29:fill%28ffffff%29 and the web server seems doesn't like it.

P.s. note that I'm not the author of these kind of urls nor able to upgrade the web-server to a recent version that probably could be able to unescape the path again.
