This url works fine in browser, but fails in Carrierwave.
Media::Image.new(remote_file_url:"http://beta.url2png.com/v4/P4FCD34DF0E055/229204fabd822ab0cd2593b8841e6013/t800x600/http://maps.google.com/maps?q=Rio+de+Janeiro%2C+Brazil")

You need to override this method to meet your needs for handling special characters in the URL:

In case someone has the same problem, put these codes in the carrierwave initializer.rb

CarrierWave::Uploader::Download.module_eval do
  def process_uri(uri)
    begin
      URI.parse(uri)
    rescue
      URI.parse(URI.escape(URI.unescape(uri)))
    end
  end
