Comment:

 Looks like this has to do with `\s` in the regexp, similarly to #11528 and
 [12501].

 To reproduce:
 {{{
 preg_match_all('/".*?("|$)|((?<=[\\s",+])|^)[^\\s",+]+/', 'נתן, קושניר,
 אנטולי', $matches);
 var_dump($matches);
 }}}

 Here's what I get on PHP 5.2.14 (Windows), PCRE 8.02 2010-03-19:
 {{{
 array(3) {
   [0]=>
   array(6) {
     [0]=>
     string(1) "�"
     [1]=>
     string(4) "תן"
     [2]=>
     string(7) "קוש�"
     [3]=>
     string(4) "יר"
     [4]=>
     string(3) "א�"
     [5]=>
     string(8) "טולי"
   }
   ...
 }
 }}}
 With the regexp from the patch:
 {{{
 array(3) {
   [0]=>
   array(3) {
     [0]=>
     string(6) "נתן"
     [1]=>
     string(12) "קושניר"
     [2]=>
     string(12) "אנטולי"
   }
   ...
 }
 }}}
