How can encoding collisions be prevented when dealing with UTF-8 and Western-ISO content in PHP forms?

To prevent encoding collisions when dealing with UTF-8 and Western-ISO content in PHP forms, you can set the character encoding explicitly in your HTML form and PHP script to ensure consistent handling of input data. 

// Set the character encoding in the HTML form
<form accept-charset="UTF-8">

// Set the character encoding in the PHP script
header('Content-Type: text/html; charset=UTF-8');
mb_internal_encoding('UTF-8');
