Description:
------------
bad enough that mb_strtoupper() don't work at all but that mb_strtolower() destroys the string is a no-go

[harry@rh:/downloads]$ cat test.php
<?php
$mb_test = utf8_encode(chr(252) . chr(246) . chr(228));
echo "$mb_test\n";
$mb_test = mb_strtoupper($mb_test);
echo "$mb_test\n";
$mb_test = mb_strtolower($mb_test);
echo "$mb_test\n";

[harry@rh:/downloads]$ php test.php

Have you checked the value of mb_internal_encoding()? You do not provide an encoding so it depends on the configuration. I suggest to provide the encoding argument to the function calls.

$mb_test = mb_strtoupper($mb_test, 'UTF-8');

As Thomas already mentioned, please check your internal encoding setting.

indeed - it needs UTF8 as explicit param - sorry for the noise - i am about writing "profile guided optimization" code-coverage for our PHP build and extend it to verify the behavior of important functions instead only blind calls for collecting profile informations

As stated by OP not a bug, but a programming error.
