Bug description: preg_match with /u gives different results for \S\S and \S{2}
Description:
------------
When using the /u modifier, preg_match, preg_match_all, and preg_replace
all give incorrect results using /\S{2}/u but work fine with /\S\S/u which
should be equivalent.
Reproduce code:
---------------
$s = "A\xc2\xa3BC";
preg_match_all('/\S\S/u', $s, $m);
print_r($m[0]);
preg_match_all('/\S{2}/u', $s, $m);
print_r($m[0]);
Expected result:
----------------
Array
(
[0] => A£
[1] => BC
)
Array
(
[0] => A£
[1] => BC
)
Actual result:
--------------
Array
(
[0] => A£
[1] => BC
)
Array
(
[0] => A
[1] =>
)
