Text selection problem with some documents #2013

Open marcoscmonteiro opened 3 years ago

marcoscmonteiro commented 3 years ago

Text selection does not work well with some documents. I'm attaching one which we can observe malfunction. This problem occurs with 3.2 version and 3.3 pre release. I'm attaching an image and PDF document with problem. In other PDF viewers (e.g. Adobe Reader) this problem does not occurs.

Without opening it, Looks like it was run through an OCR app here it is in Edge image Ok it does not say OCR but it certainly looks corrupted by reprinting (that's a very old version of PDF-Creator) perhaps needs to be resaved using PDFCreator-4.3

@kjk Garbled in Tracker eXchange and Edge I would say that MuPDF would declare this an abomination not worth fixing?

In fact mupdf-gl.exe (1.18.0) with same problem:

@kjk My view on this one is the file is corrupt in all viewers and editors thus its unfixable by MuPDF
Although Acrobat has a reasonable alignment of characters they are garbled there too image
