What are potential pitfalls when working with fonts in TCPDF and how can they be avoided?

One potential pitfall when working with fonts in TCPDF is not properly embedding the font files, which can lead to rendering issues or errors when generating PDFs. To avoid this, make sure to correctly embed the font files using TCPDF's addTTFfont() method before using the font in your PDF.

// Example of embedding a font file in TCPDF
$fontPath = TCPDF_FONTS::addTTFfont('/path/to/font.ttf', 'TrueTypeUnicode', '', 96);

// Set the font for the PDF
$pdf->SetFont('customfont', '', 12);
