Obviously you have no idea what you are talking about and obviously you
don't speak Greek or know anything about the Greek language.

The word "êéíçôÞñá" is capitalized as "ÊÉÍÇÔÇÑÁ".

What you are suggesting is like capitalizing the word "engine" as
"ENGiNE".

Obviously, there is no word "ENGiNE", same way there is no word
"ÊÉÍÇÔÞÑÁ" :)

The test case is wrong and the bug should be closed. The upper case
search target is misspelled.

$target1 = "ÊÉÍÇÔÇÑÁ";
$target2 = "êéíçôÞñá";
should read
$target1 = "ÊÉÍÇÔÞÑÁ";
$target2 = "êéíçôÞñá";

(note the replacement of the second Ç with a capital Thorn (U+00DE).

With this change I get the expected result:

Actual Result
-------------

Searching for: ÊÉÍÇÔÞÑÁ
Result string: Ôï êõñßùò ôìÞìá ôïõ itworks, áõôü ðïõ ðåñéëáìâÜíåé ôïõò
êõëßíäñïõò
Found and replaced: 1

Searching for: êéíçôþñá
Result string: Ôï êõñßùò ôìÞìá ôïõ itworks, áõôü ðïõ ðåñéëáìâÜíåé ôïõò
êõëßíäñïõò
Found and replaced: 1

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
êõëßíäñïõò
Found and replaced: 0

Searching for: êéíçôÞñá
Result string: Ôï êõñßùò ôìÞìá ôïõ itworks, áõôü ðïõ ðåñéëáìâÜíåé ôïõò
êõëßíäñïõò
Found and replaced: 1
