This looks nice. But pdf doc building failure is genuine. pdftex with inputenc package cannot handle those unicode characters. |

The chatbot is useful here too. I like solution 4. We may switch to xetex. The error you're encountering with To resolve this issue, you can try a few things:

@fchapoton - I think we should just switch to xelatex/lualatex pdf builder, AND also drop (pdf)latex builder (as inferior, obsolete 30-years old tech). I advocate for this on #36861 (@kwankyu wants to keep (pdf)latex builder - but I don't see why) |
