Continuing the discussion from Highlighting problem with certain PDFs:
I prefer highlighting on the iPad, but notice that this problem still persists on iOS. I recently found a PDF where during highlighting the selection after a certain point would suddenly jump to include a previous or following section and could not highlight the next few words (for example). The desired selection could be highlighted carefully in segments (not ideal). I tied OCR in both DT2G and DT3, as well as compress/convert to a new PDF in PDFExpert, but the problem persists on the iPad, although the highlighting process in Devonthink 3 seems just fine. I have encountered this problem before, but this time did some convert and compare.
Note: before OCR/convert, highlighting on the original extended into the document margins, and some annotations would shift to an adjacent location on reopening, and both of those problems were fixed after conversion. But the highlighting selection is still glitchy on iOS only.
Edit: I’m currently working on another PDF with the same problem, and it appears that the broken highlighting may be caused by two column justified text where word spaces are larger than some normal width.
