My application supporting multiple language.
My Controller,
 public function index(Request $request) {
    return DB::table('offer_types')
                    ->join('offer_type_details', 'offer_type_details.offer_types_id', '=', 'offer_types.id')
                    ->where('offer_type_details.languages_id', $request->language_id ? $request->language_id : 1)
                    ->get();
}
In case of Arabic, it returns following json,
    [{
    "id": 1,
    "description": "desc",
    "offer_types_id": 1,
    "languages_id": 2,
    "title": "\u062d\u0632\u0645"
}, {
    "id": 2,
    "description": "desc",
    "offer_types_id": 2,
    "languages_id": 2,
    "title": "\u0641\u0646\u0627\u062f\u0642"
}]
How can I encode this arabic value in Laravel 5.2?
