--- Comment #12 from [email protected] --- (In reply to bunkem from comment #10) > Please confirm I'm looking at the right section. Yes, you are looking at the right section. I should say that I am not aPDF expert, during accessibility checking of documents I just happened to discover that language markings of LibreOffice generated PDF files disappear after merging them with Acrobat Pro. I found out this when JAWS screen reader could no longer dynamically change the reading language according to the content. Then I just started to investigate the issue a little further. I should also mention that there are tools that can merge LO generated PDF files in a way that preserves the language tagging. One such tool is the Foxit PDF editor. https://www.foxit.com/merge-pdf/ This is propably irrelevant, but PDF 1.3 reference manual seems to indicate that in the past there has been even third way of marking the language of text. page 39, https://people.ksp.sk/~vlado/tex/pdfspec.pdf "The text may also contain an escape sequence to indicate the language of the text. This is useful when the language cannot be determined from the character codes used in the text. The escape sequence uses the Unicode hex value U+001B followed by the two ASCII codes for the language identifiers defined by ISO 639 (see Appendix I), optionally followed by the two ASCII codes for country defined by IS0 3166 (see Appendix J), followed by U+001B." -- You are receiving this mail because: You are the assignee for the bug.
