Are there any recommended best practices or resources for troubleshooting and resolving issues with character encoding in FPDF when working with Umlaute?

When working with Umlaute (special characters like ä, ö, ü) in FPDF, it is important to ensure that the character encoding is properly set to UTF-8 to display these characters correctly. One common issue is that these special characters may not display correctly due to incorrect encoding settings. To resolve this issue, you can set the character encoding to UTF-8 in FPDF by using the SetAutoPageBreak() method before adding any text to the PDF document. This will ensure that special characters are displayed correctly.

// Set character encoding to UTF-8
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', '', 12);
$pdf->SetAutoPageBreak(true, 10);
$pdf->Cell(0, 10, 'Umlaute: ä, ö, ü', 0, 1);
$pdf->Output();
