Description:
------------
In ISO-8859-9 (Turkish) the uppercase letter of "i" is a dotted
uppercase "I", the lowercase letter of "I" is a dotless "i". But
mb_strtolower() und mb_strtoupper() simply return the ASCII uppercase
or lowercase counterparts.

You get the correct result with:
setlocale(LC_ALL, 'tr_TR');
echo strtoupper('i');
echo strtolower('I');

But the wrong results with:
echo mb_strtoupper('i', 'iso-8859-9');
echo mb_strtolower('I', 'iso-8859-9');
