To use Unicode in CodeIgniter, you need to make sure that your database, configuration files, and the CodeIgniter application itself are set up to support Unicode characters.

  1. Database Configuration: First, make sure that your database and tables are configured to support Unicode characters. This can usually be done by choosing a character set and collation that supports Unicode, such as utf8mb4.


In your CodeIgniter database configuration file (config/database.php), you can set the character set and collation like this:


$db['default']['char_set'] = 'utf8mb4'; $db['default']['dbcollat'] = 'utf8mb4_general_ci';

  1. META Charset: Make sure that your view files have the correct meta charset tag in the head section of your HTML files. This will ensure that the browser understands and displays Unicode characters correctly.


<meta charset="utf-8">

  1. Internal Encoding: You can also set the internal encoding of your CodeIgniter application to utf-8 by adding the following line to your index.php file:


mb_internal_encoding('UTF-8');

  1. Config.php File: In the config/config.php file, make sure that the charset is set to 'UTF-8':


$config['charset'] = 'UTF-8';


With these steps, your CodeIgniter application should now support Unicode characters and you can use them in your views and database operations.
