Expected output & actual output

Expected output: the text in file

Code

try {
        $parser = new \Smalot\PdfParser\Parser();
        $pdf = $parser->parseFile($path);
        $text = $pdf->getText();
        return preg_replace('/\s+/', '', $text);
    } catch (Exception $e) {
        $logger = self::getLogger('pdf2text');
        $logger->warning($e->getMessage(), ['path' => $path]);
        return '';
    }

Start by running the supplied PHP example with the linked PDF, using Parser::parseFile() and then getText(), and compare the result with the PDF's visible text. Investigate the parsing path that handles this input and add a focused reproduction test if the project provides a suitable test location. Done means the linked PDF no longer produces empty extracted text while existing parsing behavior remains intact.
