How does the CodeIgniter framework handle UTF-8 characters in form inputs and outputs?

CodeIgniter handles UTF-8 characters in form inputs and outputs by setting the charset in the config file to 'UTF-8' and using the form_validation library to validate and sanitize input data. Additionally, the htmlspecialchars() function can be used to encode special characters in output data to prevent XSS attacks. 

// In the config.php file, set the charset to UTF-8
$config['charset'] = 'UTF-8';

// In the controller, use form_validation library to validate and sanitize input data
$this->load->library('form_validation');
$this->form_validation->set_rules('input_field', 'Input Field', 'required|trim|xss_clean');

// When outputting data, use htmlspecialchars() function to encode special characters
echo htmlspecialchars($output_data, ENT_QUOTES, 'UTF-8');
