New Comment:
It actually IS a PHP issue as this bug describes some software defect
in a PHP core function that is intended to deliver the functionality
described here: sorting an array on a locale-aware basis using available
system locales.
You can argue whether it's worth fixing the bug with the upcoming PHP 6
in the pipeline, but simply categorizing this as a non-PHP issue is not
correct.

Not a php issue, use intl, mbstring or wait php6.

I'm not sure it is worth fixing, for many reasons. The first is to get
it working on each system in a portable is a real pain (and as Derick
pointed out, really not only on windows).
My opinion is that all these functions should be deprecated (or
strongly recommend to do not be used for anything but ascii) in favour
of the new unicode APIs (6.x or partially with intl).

POSIX locales, don't really deal with multi byte strings like UTF8 so
well, not even on unices.

As a windows only bug assigned to the windows port maintainer.

Description:
------------
The strcoll() function for sorting comparing strings in a locale-aware
manner does not seem to work with UTF-8 encoded strings despite using
the correct Windows locale with UTF-8 codepage (65001). strcoll() always
returns 2147483647 which makes array sorting of such strings more or
less random (for example).
Running the same snippet with Windows-1252 (ISO-8859-1) encoded strings
or on a Linux machine does in fact work as expected.
Please note: for running the following reproduce code, the PHP file
must be UTF-8 encoded!
Reproduce code:
---------------
<?php
function traceStrColl($a, $b) {
$outValue=strcoll($a, $b);
echo "$a $b $outValue\r\n";
return $outValue;
}
$locale=(defined('PHP_OS') && stristr(PHP_OS, 'win')) ?
'German_Germany.65001' : 'de_DE.utf8';
$string="ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÜabcdefghijklmnopqrstuvwxyzäöüß";
$array=array();
for ($i=0; $i<mb_strlen($string, 'UTF-8'); $i++) {
$array[]=mb_substr($string, $i, 1, 'UTF-8');
}
$oldLocale=setlocale(LC_COLLATE, "0");
var_dump(setlocale(LC_COLLATE, $locale));
usort($array, 'traceStrColl');
setlocale(LC_COLLATE, $oldLocale);
var_dump($array);
Expected result:
----------------
string(20) "German_Germany.65001"
a B -1
[...]
array(59) {
[0]=>
string(1) "a"
