Filament: Malformed UTF-8 characters, possibly incorrectly encoded

[NgYueHong]

I am test use this plugin. When test use it on Laravel, it works. But when try it in Filament, it run into error of Malformed UTF-8 characters, possibly incorrectly encoded

Tables\Actions\Action::make('download')
    ->action(function ($record) {
        $customer = Invoice::makeParty([
            'name' => 'John Doe',
        ]);

        $item = Invoice::makeItem('Your service or product title')->pricePerUnit(9.99);

        return Invoice::make()->buyer($customer)->addItem($item)->stream();
    })

                        $customer = new Buyer([
                            'name'          => 'John Doe',
                            'custom_fields' => [
                                'email' => 'test@example.com',
                            ],
                        ]);

                        $item = InvoiceItem::make('Service 1')->pricePerUnit(2);

                        $invoice = InvoicesInvoice::make()
                            ->buyer($customer)
                            ->discountByPercent(10)
                            ->taxRate(15)
                            ->shipping(1.99)
                            ->addItem($item);

                        return $invoice->stream();

here is a fix to overcome the bug

Create a controller

php artisan make:controller PdfController

A route

Route::get('pdf/{order}', PdfController::class)->name('pdf');

Write the printing logic in the invoke method of the controller

use App\Models\Shop\Order;
use Barryvdh\DomPDF\Facade\Pdf;

class PdfController extends Controller
{
    public function __invoke(Order $order)
    {
        $customer = new Buyer([
            'name'          => 'John Doe',
            'custom_fields' => [
                'email' => 'test@example.com',
            ],
        ]);

        $item = InvoiceItem::make('Service 1')->pricePerUnit(2);

        $invoice = InvoicesInvoice::make()
            ->buyer($customer)
            ->discountByPercent(10)
            ->taxRate(15)
            ->shipping(1.99)
            ->addItem($item);

        return $invoice->stream();
    }
}

Instead of action(), use the url() method

                Tables\Actions\Action::make('pdf') 
                    ->label('PDF')
                    ->color('success')
                    ->icon('heroicon-s-document-arrow-down')
                    ->url(fn (Order $record) => route('pdf', $record))
                    ->openUrlInNewTab(),
