Description:
------------
PHP_SELF returns incorrect value.
I creat a folder with chinese, the path is '/confucian/西方哲学著作/', and then I check phpinfo(),I found that $_SERVER['PHP_SELF'] returns incorrect value. But folders Created in english found no errors.

Reproduce code:
---------------
file: test.php
<?php
phpinfo();
?>

The script test.php was created in a non-english folder,such as '/confucian/西方哲学著作/'.

Expected result:
----------------
/confucian/%e8%a5%bf%e6%96%b9%e5%93%b2%e5%ad%a6%e8%91%97%e4%bd%9c/test.php
or
/confucian/西方哲学著作/test.php



Actual result:
--------------
/confucian/η??՜ѧָ׷/index.php/confucian/???????1??2?-|???????/index.php
