Bug description: preg_replace with "/i" is not case insensitive
Description:
------------
preg_replace with the "/i" (case insensitive search) does not do a case
insensitive search for UTF-8 Greek characters, while it works fine for
English characters.
Reproduce code:
---------------
<?php
$string = "Ôï êõñßùò ôìÞìá ôïõ êéíçôÞñá, áõôü ðïõ ðåñéëáìâÜíåé ôïõò
êõëßíäñïõò"; // UTF-8 string in Greek language
$target1 = "ÊÉÍÇÔÇÑÁ"; // Target string to search for (capitalized)
$target2 = "êéíçôÞñá"; // Target string to search for (small letters)
$replace = "itworks"; // Replace with this string
$rc = preg_replace("/$target1/imsUu", $replace, $string, -1, $counter); //
Execute search for target1 and replace
echo "\nSearching for: ".$target1."\n"; // Report output
echo "Result string: ".$rc."\n";
echo "Found and replaced: ".$counter."\n";
$rc = preg_replace("/$target2/imsUu", $replace, $string, -1, $counter); //
Execute search for target2 and replace
echo "\nSearching for: ".$target2."\n"; // Report output
echo "Result string: ".$rc."\n";
echo "Found and replaced: ".$counter."\n\n";
?>
Expected result:
----------------
I expect the Found and Replaced to be both "1" since the expression is not
case sensitive.
Actual result:
--------------
$ php -f test.php
Searching for: ÊÉÍÇÔÇÑÁ
Result string: Ôï êõñßùò ôìÞìá ôïõ êéíçôÞñá, áõôü ðïõ ðåñéëáìâÜíåé ôïõò
