build issue - too many authors

[CaptainSifff]

I have build issues over here.... By removing some authors, the build works again. I think LateX is running out of symbols for enumerating the authors. This is the error message I get:

Missing character: There is no   (U+0020) in font [academicons.ttf]:!

! LaTeX Error: Counter too large.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.158 \begin
            {center}\rule{0.5\linewidth}{0.5pt}\end{center}
No pages of output.

@jngrad , @MakisH I would be grateful, to understand how we can solve that...

I had faced something similar with footnotes, but there it was really using symbols: https://github.com/OpenFOAM-Journal/paperLatexTemplate/pull/10

Here, the list is using numbers...

U+0020 seems to be... whitespace?!? https://en.wikipedia.org/wiki/List_of_Unicode_characters#Basic_Latin

Maybe a specific author?

P.S.: Not available for the next 2h

The U+0020 comes from academicons. They use a UTF-8 character from the reserved block (font-specific symbols) to display the icon, and a whitespace character sneaks in as a substitute. The actual issue here is that LaTeX can only have 9 footnotes per page (because there are only 9 special characters for footnotes, doesn't matter that we use numbers), or 15 with footmisc. Let me look into it.

@CaptainSifff can you please share your PDF compile command? I cannot reproduce the error with XeLaTeX. Here is what latexmk does on my machine and in GitHub Actions:

xelatex -no-pdf -halt-on-error -shell-escape -recorder --jobname="competencies"  "competencies.tex"

[MakisH]

Also works locally on my machine, with the default make target. TeX Live 2021 on Ubuntu 22.04.

[CaptainSifff]

Running 'xelatex -no-pdf -halt-on-error -shell-escape -recorder --jobname="competencies"  "competencies.tex"'
------------
This is XeTeX, Version 3.141592653-2.6-0.999995 (TeX Live 2023/Arch Linux) (preloaded format=xelatex)
 \write18 enabled.

[jngrad]

The main branch now uses pdflatex instead of XeLaTeX, author affiliations via authblk instead of footnotes, and orcidlink instead of academicons. Don't forget to delete your build folder before attempting to run the new Makefile.

Works! Thank You!
