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
?>
(PHP 4 >= 4.2.0, PHP 5, PHP 7)

?>
Return values vary in setting and getting:
<?php
echo mb_regex_encoding();
// returns encoding name as a string
