Research direction
Start in vendor/smalot/pdfparser/src/Smalot/PdfParser/Font.php and trace the Parser::parseFile/file_get_contents path for the supplied Type0 SimSun font and its ToUnicode data. Reproduce the example and compare the extracted text with the expected Chinese string; done means the parser no longer produces mojibake for this input.
