Bug #13539: uninitialized class variable @@accept_charset in #<Class:CGI> when calling CGI.unescape

[janko (Janko Marohnić)]

When I execute this script:

require "cgi/util"
CGI.unescape("foo")

On Ruby 2.3.0 this will execute just fine, but on 2.4.1 this throws an error:

`unescape': uninitialized class variable @@accept_charset in #<Class:CGI> (NameError)

This doesn't happen when I require the whole cgi.rb standard library, only when I require cgi/util.rb. The reason why I want to require only cgi/util.rb is because I need only the URI escaping/unescaping behaviour.

share @@accept_charset

• lib/cgi/{core,util}.rb: include CGI::Util not only extending, to
  share @@accept_charset class variable, so that it is always
  accessible. [ruby-core:80986] [Bug #13539]
