I saved a file named array.json on my Dropbox folder and i access to it via Dropbox API. All works fine, but when i retrieve JSON content i cannot JSON.parse that string!!

session = DropboxSession.new(APP_KEY, APP_SECRET)
session.set_access_token(ACCESS_TOKEN_KEY, ACCESS_TOKEN_SECRET)
client = DropboxClient.new(session, ACCESS_TYPE)

json = client.get_file(DIRECTORY + '/array.json')

@json = JSON.parse json
Error:

743: unexpected token at ‘{“Nome” : “Mario Rossi”,
“C.F.” : “ABCDEFGHILMNOP”,
“Booking Assistance” : “MARIO”,
“Status of reservation” : “25/11/2011”}’
JSON string is valid!! if i copy this string and paste it (manually) as parameter in JSON.parse(), json is parsed correctly!! So i think is a encoding problem…but where i wrong?

    We have abandoned the json parsing backend that is the default in Rails. The default backend is YAML based and imo a useless mess. After several gotchas parsing unicode, and dates in some cases, we discovered that the backend can be replaced via configuration.

    You can substitute the parsing backend in an initializer

    ActiveSupport::JSON.backend = "JSONGem"

    There are several gems that can be used as the backend, we just use the json gem

    gem 'json'
