What are the best practices for handling translation files and arrays in PHP frameworks like Phalcon to ensure consistent behavior across different browsers?

When handling translation files and arrays in PHP frameworks like Phalcon, it's important to ensure consistent behavior across different browsers by properly encoding and decoding special characters. One way to achieve this is by using the `json_encode` and `json_decode` functions to handle the translation arrays.

// Encoding translation array to JSON
$translationArray = ['hello' => 'Bonjour', 'goodbye' => 'Au revoir'];
$jsonTranslation = json_encode($translationArray);

// Decoding JSON back to translation array
$decodedTranslationArray = json_decode($jsonTranslation, true);
