Font Fallback Issue

• PHP Version: 8.2.5
• PDFParser Version: 2.7.0

Description:

PDF input

Personal payslip, so unable to provide, but will do what I can

Expected output & actual output

Get text seems to work, although there is some odd encoding here or there.
When trying to run getDataTm, it fails - seems it's due to a font issue.

Fatal error: Uncaught TypeError: Smalot\PdfParser\PDFObject::getTJUsingFontFallback(): Argument #1 ($font) must be of type Smalot\PdfParser\Font, null given, called in /volume1/web/devel/includes/vendor/smalot/pdfparser/src/Smalot/PdfParser/PDFObject.php on line 531 and defined in /volume1/web/devel/includes/vendor/smalot/pdfparser/src/Smalot/PdfParser/PDFObject.php on line 252 TypeError: Smalot\PdfParser\PDFObject::getTJUsingFontFallback(): Argument #1 ($font) must be of type Smalot\PdfParser\Font, null given, called in /volume1/web/devel/includes/vendor/smalot/pdfparser/src/Smalot/PdfParser/PDFObject.php on line 531 in /volume1/web/devel/includes/vendor/smalot/pdfparser/src/Smalot/PdfParser/PDFObject.php on line 252 Call Stack: 0.0019 370824 1. {main}() /volume1/web/devel/scripts/testing/pdf.php:0 0.1753 1337680 2.

It does work on another invoice I have, just not this payslip.

Code

`
use Smalot\PdfParser\Parser;
use Smalot\PdfParser\Config;

$config = new Config();
$config->setDataTmFontInfoHasToBeIncluded(true);
$parser = new Parser([], $config);

$pdf = $parser->parseFile('paySlip.pdf');
//$pdf = $parser->parseFile('Invoice INV-0007.pdf');

$text = $pdf->getText();

$debugger->force_out($text, 'Text');

$metaData = $pdf->getDetails();

$debugger->force_out($metaData, 'Meta');

$pages = $pdf->getPages();
$debugger->force_out($pages);

$pos = $pdf->getPages()[0]->getDataTm();

$debugger->force_out($pos, 'Data');	`

Start by tracing Page.php getDataTm and PDFObject.php getTextArray through getTJUsingFontFallback, using the reported stack trace as the entry point. The original payslip is unavailable, so determine how the missing font is represented and add a reproducible regression case if possible; done means getDataTm no longer fails for this input.
