You need to create the database using collation utf8_unicode_ci. Also for phpMyAdmin. After creating the database click on the operations tab at the bottom you can change the database to the utf8_unicode_ci. For more information Here

Following points required for multilingual data insert:

• Create your database with collection "utf8_unicode_ci". Basically this allows Unicode (multilingual), case-insensitive data to be saved in your database.
• Create your database table and make sure you have selected/written collection set to be "utf8_unicode_ci" for all the table fields.

• Now comes to codeigniter part and check your database config file with location as mentioned below

  application/config/database.php

Now please check & update charset & collection settings as mentioned below

$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
