What are the best practices for handling international characters in PHP arrays for JSON encoding?

When handling international characters in PHP arrays for JSON encoding, it is important to ensure that the characters are properly encoded to prevent any encoding issues or data corruption. One common approach is to use the `json_encode` function with the `JSON_UNESCAPED_UNICODE` option to encode the characters as they are without escaping them. 

// Sample PHP code snippet to handle international characters in PHP arrays for JSON encoding
$data = [
    'name' => 'Jöhn Döe',
    'country' => '日本'
];

$json = json_encode($data, JSON_UNESCAPED_UNICODE);

echo $json;
