Subject: [ruby-core:72137] [Ruby trunk - Bug #11819] [Open] URI::encode issue with the "+" character

Issue #11819 has been reported by Yacine PETITPREZ.

----------------------------------------
Bug #11819: URI::encode issue with the "+" character
https://bugs.ruby-lang.org/issues/11819

* Author: Yacine PETITPREZ
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: 
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------

`URI.encode("a+b")` returns "a+b". Mostly all web servers transform the "+" in URI parameters to space, and can create issue with base64 encoded parameters for example.

Currently we must write this: 

`args = URI.encode(args).gsub("+", "%2B")`

Also, the rfc2396 says (G. 2):

`   The plus "+", dollar "$", and comma "," characters have been added to
   those in the "reserved" set, since they are treated as reserved
   within the query component.`
