Beware, mb_regex_encoding does not support the same set of encodings as listed in mb_list_encodings.php

Example:

<?php
mb_internal_encoding
('CP936');
mb_regex_encoding('CP936'); # this line produces an error
?>

Return values vary in setting and getting:

<?php
 
echo mb_regex_encoding();
 
// returns encoding name as a string
?>

<?php
 
echo mb_regex_encoding("UTF-8");
 
// returns true (success) of false as a boolean
?>
