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
?>

To change algo the regex_encodign
<?php
echo "current mb_internal_encoding: ".mb_internal_encoding()."<br />";
echo "changing mb_internal_encoding to UTF-8<br />";
mb_internal_encoding("UTF-8");
echo "new mb_internal_encoding: ".mb_internal_encoding()."<br />";
echo "current mb_regex_encoding: ".mb_regex_encoding()."<br />";
echo "changing mb_regex_encoding to UTF-8<br />";
mb_regex_encoding('UTF-8');
echo "new mb_regex_encoding: ".mb_regex_encoding()."<br />";
?>

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
?>
