Description:
------------
Only on MacOS do PHP 4.3.3 and .4 return different 
values for parse_url(urldecode($url)) and 
urldecode(parse_url($url)) when UTF-8 characters are 
involved.

The correct result below (identical strings) comes from 
PHP 4.3.4 on Linux/x86.

Reproduce code:
---------------
$string = "file://localhost/Volumes/Second/Next/Arianne/The%20End%20of%20Evangelion%20OST/Komm,%20su%CC%88sser%20Tod.mp3";

$first_decode = urldecode($string);
$first_url = parse_url($first_decode);
$first_path = $first_url['path'];

$last_url = parse_url($string);
$last_path = $last_url['path'];
$last_decode = urldecode($last_path);

var_dump($first_path, $last_decode);
var_dump(urlencode($first_path), urlencode($last_decode));

Expected result:
----------------
string(77) "/Volumes/Second/Next/Arianne/The End of 
Evangelion OST/Komm, süsser Tod.mp3"
string(77) "/Volumes/Second/Next/Arianne/The End of 
Evangelion OST/Komm, süsser Tod.mp3"
string(95) 
"%2FVolumes%2FSecond%2FNext%2FArianne%2FThe+End+of+Evan
gelion+OST%2FKomm%2C+su%CC%88sser+Tod.mp3"
string(95) 
"%2FVolumes%2FSecond%2FNext%2FArianne%2FThe+End+of+Evan
gelion+OST%2FKomm%2C+su%CC%88sser+Tod.mp3"

Actual result:
--------------
string(77) "/Volumes/Second/Next/Arianne/The End of 
Evangelion OST/Komm, su?_sser Tod.mp3"
string(77) "/Volumes/Second/Next/Arianne/The End of 
Evangelion OST/Komm, s?sser Tod.mp3"
string(93) 
"%2FVolumes%2FSecond%2FNext%2FArianne%2FThe+End+of+Evan
gelion+OST%2FKomm%2C+su%CC_sser+Tod.mp3"
string(95) 
"%2FVolumes%2FSecond%2FNext%2FArianne%2FThe+End+of+Evan
gelion+OST%2FKomm%2C+su%CC%88sser+Tod.mp3"
