What potential issues can arise when trying to store email bodies in a JSON file for processing in JavaScript?

When storing email bodies in a JSON file for processing in JavaScript, potential issues can arise with special characters, line breaks, and encoding. To avoid these issues, it is recommended to properly escape the email bodies before storing them in the JSON file. This can be done using functions like json_encode() in PHP to ensure that the email bodies are correctly formatted and can be safely processed in JavaScript.

$email_body = "This is an example email body with special characters like \"quotes\" and line breaks.\n";
$escaped_body = json_encode($email_body);
file_put_contents('email.json', $escaped_body);
