Hi > ! Package inputenc Error: Unicode character ¬ (U+AC) > (inputenc) not set up for use with LaTeX.
Did this ever work before? I would be surprised. I always used \usepackage[utf8x]{inputenc} to get this working. And this still works the same, like with the following document \documentclass{article} \usepackage[utf8x]{inputenc} \begin{document} Hello $¬A$ World \end{document} > Removing the character works around the FTBFS, > but does not sound like the correct fix. Of course not, the proper solution AFAIK is the above.
