What are some best practices for handling UTF-8 encoding errors when using json_encode in PHP?

When handling UTF-8 encoding errors when using json_encode in PHP, it is important to ensure that the input data is properly encoded in UTF-8 before encoding it to JSON. One way to do this is by using the mb_convert_encoding function to convert the input data to UTF-8 before passing it to json_encode. 

$data = array(
    'name' => 'Álvaro',
    'age' => 30
);

// Convert data to UTF-8 before encoding to JSON
$data_utf8 = array_map('utf8_encode', $data);
$json = json_encode($data_utf8);

echo $json;
