An administrator has directly filled content into the database and formatted it as json string. However, when retrieving it from the database and parse it into json, it failed. Because when filling data directly, instead of content need to write this (\"), they just write (") the json string shield is faulty and cannot parse. How to solve this problem.
Ex:
"aaaa"dddd"aaaa" => "aaaa\"dddd\"aaaa"
