Why doesn't decodeURI(“a+b”) == “a b”?

Question

I\'m trying to encode URLs in Ruby and decode them with Javascript. However, the plus character is giving me weird behavior.

In Ruby:

[Dev]> CGI.e

You might want to look at URI.encode and URI.decode:

require 'uri'

URI.encode('a + b') # => "a%20+%20b"
URI.decode('a%20+%20b') # => "a + b"

An alternate, that I use a lot, is Addressable::URI:

require 'addressable/uri'
Addressable::URI.encode('a + b') #=> "a%20+%20b"
Addressable::URI.unencode('a%20+%20b') #=> "a + b"
