What potential issues can arise when using htmlentities in the sender and recipient names in email scripts?

When using htmlentities in sender and recipient names in email scripts, potential issues can arise if the names contain special characters that htmlentities may not handle correctly. To solve this issue, it is recommended to sanitize the input data before applying htmlentities to ensure that the names are properly encoded. 

// Sanitize sender and recipient names before applying htmlentities
$sender_name = filter_var($_POST['sender_name'], FILTER_SANITIZE_STRING);
$recipient_name = filter_var($_POST['recipient_name'], FILTER_SANITIZE_STRING);

// Encode sender and recipient names using htmlentities
$encoded_sender_name = htmlentities($sender_name);
$encoded_recipient_name = htmlentities($recipient_name);

// Use the encoded names in the email script
