php - Codeigniter active record doesn't run Queries containing Unicodes properly -

i want run query says:

select * (restaurants) restaurant_name 'دالون'

i've used active record make query, result is

select * (restaurants) restaurant_name '%\%d8\%af\%d8\%a7\%d9\%84\%d9\%88\%d9\%86%'

and database doesn't return result.

my first q change called?

and turn off?

make sure character encoding in config.php follows:

$config['charset'] = "utf-8"; 

also, want change database configs match following:

$db['default']['char_set'] = "utf8"; $db['default']['dbcollat'] = "utf8_unicode_ci"; 

hope helps!
