This is a translated language package (system/language/kurdish) for Codeigniter 2.1.3 and maybe it works for all versions, It's almost finished and ready for use.
Download the files above. Make a Folder named (kurdish) in (system/language/) and put the files you just downloaded. And now go to (application/config/) folder and open (config.php) file and find this line ($config['language'] = 'english';) now change it to this ($config['language'] = 'kurdish';).
If you have any problem with UTF-8, Just put this line of code ( header('Content-Type: text/html; charset=utf-8'); ) in (index.php) which it's in the root in the Codeigniter folder.
