Note that you might need to actually add "u" (
PCRE_UTF8) when you migrate
code from PHP5 to PHP7.
<?php
// don't work in PHP7, works fine in PHP5
$re = "/[^ \t\n](?=\n[^ \t\n])/msS";
// works in PHP7.
//$re = "/[^ \t\n](?=\n[^ \t\n])/msSu";
$subject = '
zaż
.
';
preg_match($re, $subject, $matches);
// matches supposed to get "ż"
// returns 65533 (�) in matches in PHP7
var_export($matches);
?>
