What are common issues when creating barcodes with FNC3 characters in PHP?

When creating barcodes with FNC3 characters in PHP, a common issue is that the FNC3 character may not be properly encoded or recognized by the barcode generation library. To solve this issue, you can manually encode the FNC3 character using the appropriate encoding format supported by the library. 

// Example of manually encoding FNC3 character in PHP
$barcodeData = "1234567890" . chr(0x1D); // Append FNC3 character using ASCII code
$barcode = new BarcodeGenerator();
$barcode->setText($barcodeData);
$image = $barcode->generate();
echo '<img src="data:image/png;base64,'.base64_encode($image).'">';
