That behavior is to be expected, since strcasecmp() is *not*
locale aware (it only handles ASCII characters properly regarding
case-insensivity).  That needs to be documented.

Description:
------------
---
From manual page: http://www.php.net/function.strcasecmp
---
It's the same CP1251 symbol used in test script, upper- and lower-cased

No problems if using strtolower or strtoupper, only strcasecmp is affected.

Test script:
---------------
<?
setlocale( LC_ALL, "ru_RU.CP1251", "rus_RUS.CP1251",
"Russian_Russia.1251" );
echo strcasecmp( "А", "а" );
?>


Expected result:
----------------
0

Actual result:
--------------
-32
