Are there any specific PHP configuration settings or server configurations that can impact the handling of special characters in JSON output?

Special characters in JSON output can be impacted by the PHP configuration setting `json_encode()` and the server configuration setting `default_charset`. To ensure proper handling of special characters, you can set the `default_charset` to UTF-8 in your server configuration and use the `JSON_UNESCAPED_UNICODE` flag when encoding JSON in PHP. 

// Set the default charset to UTF-8
ini_set('default_charset', 'UTF-8');

// Encode JSON with JSON_UNESCAPED_UNICODE flag
$jsonData = json_encode($data, JSON_UNESCAPED_UNICODE);
