I am working on a book that feeds on the ''Fourier'' package (I am using pdflatex not xelatex or lualatex). However, there are sections under the title ''applications'' that are desired to be of a different font.
\usepackage{fourier}
\begin{document}
...
\begin{application}
Here go say ''[english]{babel}'' package and ''{mathpazo,mathabx}'' package.
\end{application}
...
\end{document}
What I found was ''unicode-math'' which is specific to xelatex to the best of my knowledge. Any suggestions?
unicode-mathpackage -- note: it's not spelled "uni-code math" -- is not specific to XeLaTeX. It works just as well under LuaLaTeX. – Mico Nov 06 '22 at 10:33
