What are the potential pitfalls of using json_decode and json_encode in PHP?

One potential pitfall of using json_decode and json_encode in PHP is that they may not handle special characters or encoding properly, leading to data corruption or loss. To solve this issue, it's recommended to use the JSON_UNESCAPED_UNICODE option when encoding JSON data to ensure that Unicode characters are correctly handled. 

$data = ["name" => "John Döe"];
$json = json_encode($data, JSON_UNESCAPED_UNICODE);
echo $json;
