here - the problem arose with Sphinx documentation, the default<br>
documentation system in Python, which generates code for html/pdf/...<br>
For generating pdf it uses xelatex and lualatex (AFAIS ... don't bite me<br>
if I am wrong) and there are some templates that generate the documents.</blockquote><div><br></div><div>As both a TeX and Python user I can provide some more information, or at least links.</div><div><br></div><div><a href="https://docs.python.org/3/">https://docs.python.org/3/</a> states that it's generated using Sphinx 2.4.4.<br></div><div><br></div><div><a href="https://www.sphinx-doc.org/en/master/latex.html">https://www.sphinx-doc.org/en/master/latex.html</a> gives information about use of xelatex and lualatex.
