3 months ago nbconvert includes boilerplate code that uses package ucs.
There is some problem with this package and TeX engines like XeTeX that handle Unicode.
A workaround is to convert the .ipynb file to LaTeX.
Edit the .tex file and comment out or delete the line with \usepackage[...]{ucs}.
Then compile the .tex file directly.
I'm puzzled because in the file share/jupyter/nbconvert/templates/latex/base.tex.j2 in this repository, the line for \usepackage[...]{ucs} is inside of \ifPDFTex ... which should fix this problem.
It looks like commit 5fe7c81 specifically fixed this problem, and it's dated 2021.
However, in version 7.16.0 of nbconvert, which is what I got with pip install --user nbconvert, that file is rather different and the line for \usepackage[...]{ucs} is executed unconditionally.
I ran pip install --user -U nbconvert and it updated to version 7.16.4 of nbconvert, and that version includes the fix, and I can convert my notebook directly to PDF.
Hello today I did the following installations brew install --cask mactex-no-gui pip install nbconvert PyPDF2
I can find nbconvert and pyPDF2 in my anaconda (base) environment. However, I failed to convert a very simple .ipynb file with print('hello world') to pdf. The error message is as follows. As a beginner, I may have made basic mistakes in this process. I would appreciate your guidance on fixing that.
