here is a simple test case using the internal class PharFileInfo
<?
$class = 'PharFileInfo';
echo 'Locale: '.setlocale(LC_ALL, '0')."\n";
echo "$class exists? ".var_export(class_exists($class), true)."\n";
echo 'Locale: '.setlocale(LC_ALL, 'tr_TR.UTF-8')."\n";
echo "$class exists? ".var_export(class_exists($class), true);
?>
Output:
Locale: C
PharFileInfo exists? true
Locale: tr_TR.UTF-8
PharFileInfo exists? false

No, the problem results because lowercase i (in most languages) and uppercase I
(in most languages) are not actually considered to be the upper/lower variant
of
the same letter in Turkish. In Turkish, the undotted ı is the lowercase of I,
and the dotted Ä° is the uppercase of i. If you have a class named Image, it
will break if the locale is changed to turkish because class_exists() function
uses zend_str_tolower(), and changes the case on all classes, because they are
supposed to be case insensitive. Someone else above explained it very well:
class_exists() function uses zend_str_tolower(). zend_str_tolower() uses
zend_tolower(). zend_tolower() uses _tolower_l() on Windows and tolower() on
other oses. _tolower_l() is not locale aware. tolower() is LC_CTYPE aware.
Please, oh please, can someone fix this already? It has been a very long time
and it's extremely annoying and difficult to work around if you have a large
multilingual website.

I am sorry to ask this for my understanding:
Is it true, that the cause for this bug lies in a false inclusion of the "I"
character in the Turkish character set - and therefore results in an
unnecessary replacement?
If so, my green knowledge leads me to the assumption, that a fix should be
rather simple.
**duck**,
