It looks like you're trying to use a multi-byte encoded character, in UTF-8.
strtolower and the other core PHP string functions can't handle multibyte, so
it may well be that strlower is changing the case of the string character by
character - which won't work for UTF-8, even if you've set the locale.

You might have more luck with the mbstring functions, like:
http://uk3.php.net/manual/en/function.mb-strtolower.php

Try the following:

<?php
header("Content-type: text/html; charset=utf-8");

setlocale(LC_ALL, "pl_PL.UTF-8");

// UTF-8 encoded Polish characters
$chars = array(
chr(0xC4) . chr(0x85),
chr(0xC4) . chr(0x99),
chr(0xC3) . chr(0xB3),
chr(0xC4) . chr(0x87),
chr(0xC5) . chr(0x82),
);

print "<pre>";

foreach ($chars as $c)
{
print $c;
print " strtoupper: ";
print strtoupper($c);

print " mb_strtoupper: ";
print mb_strtoupper($c, 'UTF-8');

print "<br>";
}

print "</pre>";
?>
