How can the issue of displaying "B�cher" instead of umlauts be addressed when switching to UTF-8 encoding?

The issue of displaying "B�cher" instead of umlauts when switching to UTF-8 encoding can be addressed by ensuring that the PHP file is saved with UTF-8 encoding and that the HTML meta tag specifies UTF-8. Additionally, using the mb_internal_encoding() function in PHP to set the internal encoding to UTF-8 can help resolve this issue. 

<?php
// Set internal encoding to UTF-8
mb_internal_encoding('UTF-8');

// Output UTF-8 encoded text
echo "Bücher";
?>
