How to make PREG_MATCH work correctly with Cyrillic?

Question

PHP

Friends, there is a problem with preg_match:

$string = '10-я Соколиной Горы';
preg_match("/[*\d][*\d]-[*\W]/", $string, $math);
print_r($math);

It finds a match, but print_r returns the found substring like this:
Array
(
[0] => 10-�
)
How to treat? The script itself and the string in UTF8
