Fwd: Pdf-writer, tagged pdf?
2016-04-12 14:58:33 GMT
When I produce a PDF with TeXmacs (latest from svn) and use the "read aloud" feature of pdf-max pro on Android, it doesn't "see" the typographic ligatures, and pronounces words wrong. For example, "offense" becomes "o ense", dropping the "ff" ligature. I wrote to the author of the pdf-writer library that TeXmacs uses after reading a little about the problem using a Google search, and learning that there exists something called "tagged pdf" which I don't know much about yet; I'm too busy to read about it as much as I'd like to.

I wonder if it supports creation of "tagged pdf"? My interest is due to your library being used by the TeXmacs editor, and when I export to pdf and have the pdf reader app perform text to speech (read aloud) it skips typographic ligatures and thus mispronounces words that contain them. I think the solution involves emitting tagged pdf that has typographic ligatures transliterated to their multi character unicode equvalent for the voice-reader and highlight + clipboard, while still using the ligature for display and printing.
