Ruby 2 and Rails 4 encoding issue

Question

I'm working on a project that is migrating from a rails 3.2 and ruby 1.9.x to ruby 2.2.x and rails 4.2.4 version.

When the project goes to production server, it started to throw encoding errors like this:

"\xC3" from ASCII-8BIT to UTF-8

followed by an stacktrace like:

["/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/core_ext/object/json.rb:34:in `encode'"

 "/var/www/suba/app/controllers/call_center/chat_controller.rb:6:in `transcript'"

and the chat_controller.rb line 6 on transcript method:

  def transcript
    Resque.enqueue(Chat::SessionTranscript, read_request_body)
    head :ok
  end

  def read_request_body
    xml = request.body.read
    Rails.logger.info("XML: #{xml}")
    xml
  end

In another point of our code base we solved this issue using a code like:

string.encode("UTF-8", :invalid => :replace, :undef => :replace, :replace => "?")

but the same error starts to appear in other parts.

Have anyone passed for this and how are you dealing with?

Thank you in advanced.

I solved this issue by replacing like 34 at

(...)/activesupport-4.2.4/lib/active_support/core_ext/object/json.rb

for:

self.force_encoding('utf-8').to_json_without_active_support_encoder(options)
