Why Adobe Acrobat Reader works fine and shows: PROTOKÓŁ ąśęćółń ĄŚĘĆÓŁŃ aar ?

GitHubRulesOK commented 1 year ago

Posibly the author only wants to work with Adobe and not other apps like 70% of the market e.g. Edge where its worse than SumatraPDF guesses. image image

I don't understand. Foxit Reader displays correctly, Sumatra v. 3.0 displays correctly too ! Some internet tools, e.g. https://www.i2pdf.com/ displays correctly, Could you write what exactly is wrong, how the correct file should look like? In my Edge works too ! aaaz

Hmm your Edge is Polish so understands badly defined local language characters. That would be why your machine can show Polish and other regions cannot, But part of the issue Will be that current SumatraPDF does not handle all poor / loose font definitions

@kjk reopening as this is clearly a MuPDF regression not able to correct a bad file compared to other viewers
