How would I do that? Do you have a running instance somewhere? (Otherwise it'd just be simpler for you to download the file in the top comment and check if...

Ah, I found the pre-built binary. Yes, that seems to extract the numbers correctly from the linked file (where `pdfalto` HEAD fails). (Curiously, `pdfalto` works fine for a PDF --...

That doesn't do anything for me? (Weird that calling the bundled `pdfalto` on the same file then produces an XML with correct reference numbers, where locally built `pdfalto` fails.)

This seems only to apply to older PDFs from arXiv such as the one in the first comments; current (late 2022+) PDFs seem to work fine.

Seems only to be `8`, from what I can tell (which breaks detection of years and pages etc.) (Ligatures are annoying but don't break the number format, so less problematic.)

Does this help? https://tug.ctan.org/fonts/libertine/latex/LinLibertine_R.tex (The font name for math should be `nxlmi` and `ntxsy*`.)

The `8` is the big issue, since it breaks metadata detection. The rest is just nice to have (with the ligatures being the most bang for the buck).

Oooh, `taboldstyle`. That sounds like a font error...
