Description:
------------
I really like this extension and it works perfect on my old system. However, on my new system I cannot get it to work!
PHP-Scripts that use the "transliterate"-function simply do not have any output, no error message, nothing. Simply a plain white page. Maybe it is because of PHP5?

Reproduce code:
---------------
$string=iconv("utf-8", "ucs-2", $string);
$string=transliterate($string, array('diacritical_remove'));
$string=iconv("ucs-2", "utf-8", $string);


Expected result:
----------------
$string

Actual result:
--------------
*NOTHING*

Ok it's not PHP5. Where could I find error messages?

[2007-06-25 03:48 UTC] mail at webgear-office dot com

Now I found a error message in the Apache log: everytime "transliterate" is executed in a PHP script and I get the white screen, the following line is added to Apache error log:

FATAL:  emalloc():  Unable to allocate 140733193388072 bytes

[2007-06-28 03:18 UTC] mail at webgear-office dot com

Script:
-------


$string = "abcdefgh";
$res = transliterate($string, array('han_transliterate', 'diacritical_remove'), 'utf-8', 'utf-8');
echo $res;
