write a PDF file in Arabic using PHP - php

Question

I have added PHP code to generate a PDF file in Arabic and English, but when content is in Arabic it shows like this php arabic output :
I have checked the font i'm using is compatible with the Arabic language. I am not sure what I am missing. I also have the unicode to be UTF-8 in my configuration file.
here is the code
<?php
$paid_amount = $this->invoice_model->calculate_to('paid_amount', $invoice_info->invoices_id);
$client_info = $this->invoice_model->check_by(array('client_id' => $invoice_info->client_id), 'tbl_client');
if (!empty($client_info)) {
$currency = $this->invoice_model->client_currency_sambol($invoice_info->client_id);
$client_lang = $client_info->language;
} else {
$client_lang = 'arabic';
$currency = $this->invoice_model->check_by(array('code' => config_item('default_currency')), 'tbl_currencies');
}
unset($this->lang->is_loaded[5]);
$language_info = $this->lang->load('sales_lang', $client_lang, TRUE, FALSE, '', TRUE);
$payment_status = $this->invoice_model->get_payment_status($invoice_info->invoices_id);
$uri = $this->uri->segment(3);
if ($uri == 'invoice_email') {
$img = base_url() . config_item('invoice_logo');
} else {
$img = $_SERVER['DOCUMENT_ROOT'] . '/' . config_item('invoice_logo');
$a = file_exists($img);
if (empty($a)) {
$img = base_url() . config_item('invoice_logo');
}
}
?>
