Description
Hi,
First of all, good job on this tool. It really suits for what i'm trying to do.
I am trying to upload and parse pdfs for data processing. To do so, I upload and search for key-words in the text retrieved with PdfParser in order to move them in the right folder (1st step of processing). I have no trouble using this for small files (approximately < 15Mo). However, when files are bigger than that, the text generated by $pdf -> $getText() is somehow bugged. Occurences of characters like "!"#$"%&!"!''$(%&#$)%&!")'$*+ (%!,-$" appear and it doesn't seem to display the text in the right order.
I can't figure out the reason. Do you have any ideas ?
Thanks you in advance,
Best regards,
Thibaut

Research direction
Reproduce the report by parsing PDFs below and above approximately 15 MB with PdfParser and comparing the text returned by getText(). Inspect the extraction path for the malformed character occurrences and ordering differences; done means large PDFs produce readable text in the expected order without the reported artifacts.
