What are the potential pitfalls of using json_encode and json_decode consecutively?

When using json_encode followed by json_decode consecutively, there is a risk of losing data integrity due to the encoding and decoding process. This can result in unexpected behavior or data corruption. To avoid this issue, it is recommended to use the JSON_UNESCAPED_UNICODE option when encoding the data to preserve Unicode characters. 

$data = ['name' => 'JohnDoe', 'age' => 30];
$json = json_encode($data, JSON_UNESCAPED_UNICODE);
$decodedData = json_decode($json, true);

var_dump($decodedData);
