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 Previous Comments: ------------------------------------------------------------------------ [2009-02-23 13:32:39] sehh at ionos dot gr 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.
