Description:
------------
Accented characters are not properly sorted. For example, the right sorting of "?" is between "a" and "b", for "?" it's between "e" and "f", and so on...

Reproduce code:
---------------
$table = array("AB" => "Alberta",
               "BC" => "Colombie-Britannique",
               "MB" => "Manitoba",
               "NB" => "Nouveau-Brunswick",
               "NL" => "Terre-Neuve-et-Labrador",
               "NS" => "Nouvelle-?cosse",
               "ON" => "Ontario",
               "PE" => "?le-du-Prince-?douard",
               "QC" => "Qu?bec",
               "SK" => "Saskatchewan",
               "NT" => "Territoires du Nord-Ouest",
               "NU" => "Nunavut",
               "YT" => "Territoire du Yukon");
asort($table);

Expected result:
----------------
array(13) { ["AB"]=>  string(7) "Alberta" ["BC"]=>  string(20) "Colombie-Britannique" ["PE"]=>  string(21) "?le-du-Prince-?douard" ["MB"]=>  string(8) "Manitoba" ["NB"]=>  string(17) "Nouveau-Brunswick" ["NS"]=>  string(15) "Nouvelle-?cosse" ["NU"]=>  string(7) "Nunavut" ["ON"]=>  string(7) "Ontario" ["QC"]=>  string(6) "Qu?bec" ["SK"]=>  string(12) "Saskatchewan" ["NL"]=>  string(23) "Terre-Neuve-et-Labrador" ["YT"]=>  string(19) "Territoire du Yukon" ["NT"]=>  string(25) "Territoires du Nord-Ouest"}

Actual result:
--------------
array(13) { ["AB"]=>  string(7) "Alberta" ["BC"]=>  string(20) "Colombie-Britannique" ["MB"]=>  string(8) "Manitoba" ["NB"]=>  string(17) "Nouveau-Brunswick" ["NS"]=>  string(15) "Nouvelle-?cosse" ["NU"]=>  string(7) "Nunavut" ["ON"]=>  string(7) "Ontario" ["QC"]=>  string(6) "Qu?bec" ["SK"]=>  string(12) "Saskatchewan" ["NL"]=>  string(23) "Terre-Neuve-et-Labrador" ["YT"]=>  string(19) "Territoire du Yukon" ["NT"]=>  string(25) "Territoires du Nord-Ouest" ["PE"]=>  string(21) "?le-du-Prince-?douard" }

With what locale do you expect that output?
 [2005-03-07 23:49 UTC] derick@php.net 
No bug here, the functions don't understand locales unless you add as second "sort-flag" parameter SORT_LOCALE_STRING to asort(). This option is introduced in PHP 5.0.2.

The following works fine (if you have the fr_FR locale installed):

<?php
setlocale(LC_ALL, 'fr_FR');
$table = array("AB" => "Alberta",
"BC" => "Colombie-Britannique",
"MB" => "Manitoba",
"NB" => "Nouveau-Brunswick",
"NL" => "Terre-Neuve-et-Labrador",
"NS" => "Nouvelle-?cosse",
"ON" => "Ontario",
"PE" => "?le-du-Prince-?douard",
"QC" => "Qu?bec",
"SK" => "Saskatchewan",
"NT" => "Territoires du Nord-Ouest",
"NU" => "Nunavut",
"YT" => "Territoire du Yukon");
asort($table, SORT_LOCALE_STRING);
var_dump($table);

It's a bug if *sort() functions can't handle locales correctly.
 [2005-03-08 23:17 UTC] derick@php.net 
No bug here, PHP 4 never had support for sorting locale based. I added this function to PHP 5.0.2 to support it.
 [2005-03-08 23:33 UTC] sniper@php.net 
Saying that something is supported in PHP 5 isn't gonna make this 'feature' (or fix, IMO) end up in PHP 4. Backport it is.

Derick, so is it a bug or not?
 [2005-04-05 11:16 UTC] derick@php.net 
Not a bug, but Jani committed my backported addition to 4.3.12.
