This is unlikely to be a native PHP issue. Can you perform a similar test using
the pcretest program from pcre.org? If you can reproduce it with that then it
takes PHP completely out of the picture and you would need to file it against
libpcre.

Please note that I am aware that using a regex without the "u" modifier with non-
standard characters is discouraged. HOWEVER, it is still bad for there to be
different behavior in Windows than in Unix.

Description:
------------
In limited circumstances, PHP is mangling certain UTF8 strings in Windows. The
same issue is not appearing in SunOS, and probably not in Linux either (I would
have to reboot to double check that, but I've never seen the issue in the many
times I've run the script in Ubuntu).
Test script:
---------------
$text = "{{ááá¤áá áááªáá |
áá¦á¬áá á = á¡ááá¦ááá á
ááááá á¯ááá¡
áá£á®á£á ááá | á¬á§áá á = |
ááá áá¦á = | ááá¢áá á =
[[áááá®ááá ááááá:lika";
echo preg_replace("/\s+/", " ", $text);
Expected result:
----------------
Expected result, observed on a SunOS, i386, PHP 5.3.8 (without quotes):
"{{ááá¤áá áááªáá |
áá¦á¬áá á = á¡ááá¦ááá á
ááááá á¯ááá¡
áá£á®á£á ááá | á¬á§áá á = |
ááá áá¦á = | ááá¢áá á =
[[áááá®ááá ááááá:lika"
Actual result:
--------------
Observed result in Windows 7, WOW64, PHP 5.3.14 (without quotes):
"{{ááá¤áâ áááªáá |
áá¦á¬áâ á = á¡ááá¦ááâ á
ááááâ á¯ááá¡ áá£á®á£â
ááá | á¬á§áâ á = | ááâ áá¦á = |
ááá¢áâ á = [[áááá®ááâ
ááááá:lika"
