Are there any best practices or guidelines to consider when working with custom fonts in PDFlib using PHP?
When working with custom fonts in PDFlib using PHP, it is important to ensure that the font files are properly embedded in the PDF document. This can be done by specifying the font file path and using the `set_font()` method in PDFlib to set the custom font for text output.
// Specify the path to the custom font file
$fontPath = 'path/to/custom/font.ttf';
// Load the custom font file
$font = $p->load_font('TrueType', $fontPath, 'unicode');
// Set the custom font for text output
$p->set_font($font, 12);
