How can one troubleshoot issues with PHP-generated PDFs displaying incorrectly?

Issue: If PHP-generated PDFs are displaying incorrectly, it could be due to issues with the PDF library being used, incorrect encoding, or missing fonts. To troubleshoot, try updating the PDF library, ensuring proper encoding of text and images, and including necessary fonts in the PDF generation process. Code snippet: 

// Example code using TCPDF library to generate PDF with proper encoding and fonts
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->SetFont('dejavusans', '', 12);
$pdf->AddPage();
$pdf->SetTextColor(0, 0, 0);
$pdf->Write(0, 'Hello World', '', 0, 'L', true, 0, false, false, 0);

$pdf->Output('example.pdf', 'I');
