@barbarabeeton Indeed, I guess the 0,994 is an answer @UlrikeFischer forgot to finish writing. Almost at 5 though.

@AlanMunn -- If that were a period it would round up to exactly 5.

@barbarabeeton Rounding schmounding. Where's the fun in that. :)

@AlanMunn -- Rounding is a lot easier unless you're plotting on really teeny-tiny graph paper.

Just an update on an earlier qiscussion regarding LaTeX not being allowed in health PhD dissertations. The student asked the library and got the answer that their problem was when copying the text from PDF into Word, then the words were not separated correctly. Whether this was the case for this student as well, we don't know . The student added a few extra pages to their dissertation using Acrobat and apparently they had no issue processing it.

So my guess is what I think David mentioned: The library may have had a bad experience with a LaTeX file once, and just banned then for good. They should probably reconsider.

Additionally why are they copying the text into Word? From the homepage of that anti plagiarism tool it seems to be able to handle PDFs directly.

@daleif It's always unfortunate when people prefer Word over TeX.

@FaheemMitha I don't think preference is the correct term here, more that some people don't understand that there are other tools than Word.

@daleif Perhaps you are right.

@daleif well lots of people (including me) do copy&paste from a pdf once in a while. And it can be a problem if spaces are lost, as as TeX by default doesn't use real spaces chars but only glue it can happen easily. With pdflatex you can try \pdfinterwordspaceon to improve things, with lualatex you can use the code in tagpdf (also without tagging). Both will add real space chars.

would \pdfinterwordspaceon change anything visually of the PDF?

@daleif no it shouldn't have visual effects. Space could appear in wrong places see e.g. github.com/u-fischer/tagpdf/issues/34, and as the space char is actually quite small and from a different font e.g. reflow in adobe doesn't work well with (but there is just some discussion going on if that can be improved).

@UlrikeFischer we could have xlualatex emulating lualatex with pdflatex so boldmath worked

@DavidCarlisle ;-)

@DavidCarlisle Bold math is not working in luatex?

@mickep it works brilliantly but has some features some people don't expect github.com/wspr/unicode-math/issues/512 and tex.stackexchange.com/q/673839/1090

@DavidCarlisle oh, so more a unicode-math problem?

@mickep yes

@daleif -- It used to be that spaces were represented in dvi files by explicit "movement" of the starting character of the next word, rather than the presence of a space character. When this was realized (because someone complained to DEK that searches for consecutive words didn't work), the problem was fixed. I don't remember when that was, but it's not a problem now.

@barbarabeeton it's still a problem by default, pdftex has \pdfinterwordspaceon but that is off in latex by default

@DavidCarlisle -- Can you discuss that with Karl? I thought it was fixed generally. Karl knows the details. It would be good to get rid of the problem forever.

@barbarabeeton I (and Ross) reported some problems some time ago and we are just discussing improvements with Hàn Thế Thành and Karl. But the main problem is, that the main encodings in LaTeX (OT1, T1, LGR, T2n) all have no space in position 32 and so the best fix (roughly: "use the space char from the font") would work only with LY1.

Any TeXShop users having problems with the preview of a document being completely missing, i.e. the tab is there but just a grey background with no pages even the the document is openable in e.g. Skim? It's not all documents, but I can't figure out a pattern.
