OCR errors on pre-generated pdf's

[davidmlafuente]

Hi all!,

This is my first post here after deploy paperless-ng for my own paper management and (of course) I have a problem.

Frecuently, I receive the invoices for power supply on my email and I want to store it on paperless. In this case, I put some of these invoices at the consume folder and paperless catch all fine but when I go to the "Content" tab of a document I see the following text:

(cid:2)(cid:3)(cid:4)(cid:5)(cid:6)(cid:7)(cid:8)(cid:9)(cid:10)(cid:5)(cid:11)(cid:12)(cid:13)(cid:7)(cid:14)(cid:7)(cid:15)(cid:6)(cid:3)(cid:16)(cid:17)(cid:18)(cid:6)(cid:9)(cid:10)(cid:15)(cid:19)(cid:7)(cid:20)(cid:21)(cid:22) (cid:9)(cid:19)(cid:20)(cid:12) (cid:23)(cid:24)(cid:25)(cid:26)(cid:27)(cid:26)(cid:25)(cid:28)(cid:26)(cid:29)

If I put a pdf generated from my scanner, everything goes well and ocr works fine. Even if I put other web-app-generated pdf from another supplier, it works fine.

So I thing that the problem could be the way my power supplier generates the pdf on their application.

i figure that talking with the company will not solve anything, but... anyone knows what I can do to solve this?

I attached a screenshot that shows the problem.

Thank to all for your time!!

*** UPDATE ***
Sorry, I made a mistake. PDF file wasn't go directly from the email to paperless. in this case, I received a lot of invoices in the same pdf file and I use macOS preview app to separate the file in different files, one per invoice.
So i´ve thinked... well, maybe if I go to my supplier webpage and download one invoice from the customer panel.... without touch anything... MAYBE it can work. but no. It throws me other error.
