What are some common pitfalls when using tcpdf and fpdi with UTF-8 encoding in PHP?

One common pitfall when using TCPDF and FPDI with UTF-8 encoding in PHP is that special characters may not be displayed correctly in the generated PDF. To solve this issue, you can set the TCPDF font to support UTF-8 characters by using the addTTFfont method to add a TrueType font file that includes the necessary characters.

// Set TCPDF font to support UTF-8 characters
$font_path = TCPDF_FONTS::addTTFfont('/path/to/your/font.ttf', 'TrueTypeUnicode', '', 96);

// Use the font in TCPDF
$pdf = new TCPDF('P', 'mm', 'A4', true, 'UTF-8', false);
$pdf->SetFont($pdf->addTTFfont($font_path), '', 12);

// Generate PDF content using FPDI and TCPDF
