What is the significance of the Euro symbol in form input values and how does it affect PHP processing?

The Euro symbol (€) in form input values can cause issues when processing PHP due to character encoding differences. To properly handle Euro symbols in form input values, it is important to ensure that the correct character encoding is set and that the Euro symbol is properly sanitized before processing. 

// Set the character encoding to UTF-8
header('Content-Type: text/html; charset=utf-8');

// Sanitize the form input value containing the Euro symbol
$input_value = filter_input(INPUT_POST, 'input_field', FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH);

// Process the sanitized input value
// For example, save it to a database
