in new k2 release (2.7) when you search about something arabic characters on backend , nothing is happened ,
i solve this solution and want to share it here :
it is because of triming and replacing your character to null ,
go to this path : administrator/components/com_k2/models/items.php
in line 40 you will see this :
$search = trim(preg_replace('/[^a-zA-Z0-9\s\-_]/', '', $search));
comment this line , like this :
//$search = trim(preg_replace('/[^a-zA-Z0-9\s\-_]/', '', $search));
everything will be work good ,
i think k2 have to change regex .
thanks .
