@cyberorg where you able to build the PDF in your own computer? I just downloaded the code and was able to build the HTML but I had a different problem with the PDF:

******** ERROR !! PLEASE UPDATE titlesec.sty !!********
******** THIS VERSION SWALLOWS SECTION NUMBERS.********.

Yes, using this in conf.py

latex_elements = { 'preamble': '''

\usepackage{fontspec} \setsansfont{FreeSans} \setromanfont{FreeSerif} \setmonofont{FreeMono} ''', } and then running the following:

make -e SPHINXOPTS="-D language='gu'" latex cd build/latex/ xelatex *.tex

This creates the pdf.

I see. That seems to be a very custom way to generate your PDF file which is not setup in RTD. You could try to do some magic in your conf.py that RTD will execute by you and try different options.

Using xelatex instead of pdflatex seems to be the only way to generate pdfs of "non-english" language, I am sure this affects every Indian languages(there are 15 official ones) and all other languages using unicode characters.

Is there way to add that magic of using xelatex in place of pdflatex to conf.py?

Here is the less custom option that also works, we just need option to set PDFLATEX=xelatex on readthedocs:

make PDFLATEX=xelatex -e SPHINXOPTS="-D language='gu'" latexpdf
