        if ($order->discount > 0) {
            $invoice->totalDiscount($order->discount);
        }

        // Kargo ücreti
        // if ($order->shipping_cost > 0) {
        //     $invoice->shipping($order->shipping_cost);
        // }

        // return $invoice->stream(); // PDF olarak görüntüle
        // Alternatif olarak:
        // return $invoice->download(); // PDF'i indir
        // $invoice->save('storage/invoices'); // Depolama alanına kaydet


        // UTF-8 headers for PDF response

i tried this functions:

• mb_convert_encoding
• htmlspecialchars
• mb_strtoupper(mb_substr($variable, 0, 1)

database charset and collation:

MariaDB [xxxxxxxxxxx]> SELECT @@character_set_database, @@collation_database;
+--------------------------+----------------------+
| @@character_set_database | @@collation_database |
+--------------------------+----------------------+
| utf8mb4                  | utf8mb4_unicode_ci   |
+--------------------------+----------------------+

i tried this commands:

• artisan optimize:clear
• artisan view:clear
• artisan config:clear
• artisan cache:clear

1. Go to '...'
2. Click on '....'
