New Comment:
The strnatcmp uses the zend_parse_paramters function to parse the
function parameters. The zend_parse_parameters function converts the
string from php space into a char. Seeing as how this is a core
function, I doubt this will be fixed soon.
I may be completely off base, so I will leave this bug open in case
someone else wants to comment.

Description:
------------
Hello,
why is the nat_char defined as char instead of unsigned char?
char limit us (and a correct sorting) to ASCII 0-127. With a unsigned
char (ASCII 0-255) the sorting is "correct" for all single byte charsets
like iso-8850-1 (which is the default in PHP).
Internally the function is already doing a cast to unsigned char many
times (but not in the main comparison).
In the original header (strnatcmp.h) from the author, the typedef for
nat_char is also only a hint.
Regards,
Carsten
Reproduce code:
---------------
<?php
$daten = array('Süden','spielen','Sonne','Wind','Regen','Meer');
natcasesort($daten);
print_r($daten);
?>
Expected result:
----------------
Array
(
[5] => Meer
[4] => Regen
[2] => Sonne
[1] => spielen
[0] => Süden
[3] => Wind
)
Actual result:
--------------
Array
(
[5] => Meer
[4] => Regen
[0] => Süden
[2] => Sonne
[1] => spielen
[3] => Wind
)
