When this function is perfected, and is not experimental, it may be very usefull in the searching and pinpointing of places inside large text files.

I simulated it:
<?php
$text = 'Äpfel';
mb_internal_encoding( 'utf-8' );
printf( "%d\n", mb_eregi( 'äpfel', $text ) ); // Output: 0
printf( "%d\n", mb_ereg( 'äpfel', mb_strtolower( $text ) ) ); // Output: 1
printf( "%d\n", mb_eregi( 'äpfel', mb_strtolower( $text ) ) ); // Output: 1
?>
