Let me say few words on preference for lualatex. Once I heard about Kwankyu's PR, I immediately suggested that should be luatex, not xetex. After trying xetex he decided to switch it to luatex. 1) lua(lat)tex is the official TexLive's successor of pdf(la)tex. It has proper unicode support, one can use unicode maths, etc. luatex is packaged better within TeXLive too. 2) xelatex has been in maintenance mode for some year by now, and it's unicode support is a bit funny. (in pdflatex it's next to nonexistent) 3) For building sagemath PDF docs it doesn't matter much, one doesn't do it often, it's not instant. Using unicode in docstrings makes them more readable and faster (less MathJax). OTOH Sage's view() might need the speed, but you can change what engine you use there irrespective of what's used for building the docs.
