What considerations should be made for forms on a multilingual PHP website to support UTF-8?

When working with forms on a multilingual PHP website to support UTF-8, it is important to ensure that the form data is properly encoded and processed to handle special characters from different languages. This can be achieved by setting the character encoding to UTF-8 in both the HTML form and the PHP script that processes the form data. Additionally, using functions like htmlspecialchars() and htmlentities() can help sanitize and display the input correctly. 

// Set UTF-8 encoding in HTML form
<form accept-charset="UTF-8">
  <!-- form fields here -->
</form>

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

// Sanitize form input
$input = htmlspecialchars($_POST['input_field'], ENT_QUOTES, 'UTF-8');
