Question PDF with ligatures -> EPUB/MOBI etc.

I have a PDF book, it's 1.3MB and text is selectable. I want to be able to change formatting to use it with Cool Reader for Android. Unfortunately, it contains ligatures (for instance, "Th" is a single character) and they're absent from the output after converting the file to EPUB, MOBI etc. with Calibre.

I used Microsoft's print to PDF function to make it more compatible with Calibre because I read somewhere that it could work. Unfortunately, it looks like this simply converted every single page to raster images because the output is 400MB. Also, I can copy and paste pages into Photoshop by simply right clicking a page in SumatraPDF and selecting "copy image".

Can someone help me out? I'd be okay even with something as basic as plain text. The problem is still the ligatures. I never had to deal with them and now I think they were invented just to make people's lives harder.

If you have MS Word 2016 or later, try opening the PDF in Word and then save as DOCX and get calibre to convert the DOCX to EPUB/AZW3 whatever. You might be able to 'deal' with the ligatures in Word.

I opened it in Word 16.0 (latest release) and the ligatures were already gone.
