Hi Leo not suggesting anything... just exploring alternatives. I too have a lot of UTF-8 in my documents and pdf-latex chokes at them, too. I'm not using preview -have never been- because my field of research didn't need complex math in my papers. Thanks for your feedback :-) /PA On Sat, 12 Apr 2

Oops, my mistake. I was actually calling `luatex' instead of `lualatex'. The document compiles fine with `lualatex'. However, noted, it did take noticeably longer. Thanks, Rohit

Re: [DISCUSSION] Setting LuaLaTeX as default when exporting to LaTeX/PDF

More to the point - users can already choose what they want for a compiler. There could even be suggestions as to the most appropriate compiler for given tasks in the documentation. But leave the default alone.

Hi. My context: ever since I started with my PhD Thesis some 15 years ago, I have been using LaTeX. I got into org-mode when I had to prepare a couple of interactive presentations to help people understand Python. Changing code and executing on the fly was the killer app for me. I use utf8, so I

Re: [DISCUSSION] Setting LuaLaTeX as default when exporting to LaTeX/PDF

So we are torn between two equally potent arguments. If you want/need latex-preview, forget about lualatex, but then restrict yourself to character sets it handles and forget about fancy utf8 support. If you want/need utf8 support, forget about latex-preview and compilation speed (at least FTMB) L

Re: [DISCUSSION] Setting LuaLaTeX as default when exporting to LaTeX/PDF

Karthik, thanks for the email, including those screencasts. You are right, lualatex is too slow for use in generating previews. Do you have any ideas about how we could improve the handling of utf-8 without sacrificing the speed of the preview system? Leo On Wed, Apr 02 2025, Pedro Andres Aranda

Re: [DISCUSSION] Setting LuaLaTeX as default when exporting to LaTeX/PDF

Thanks for the complete explanation. This is an argument with real weight and I fully understand. That lualatex is slower to start up is something even the overleaf.com people are struggling with. So we have to live with weak UTF.8 support w/preview versus good UTF-8 support with slw preview (
