I am using the Accanthis font in XeLaTex and it has unfortunate ligatures, especially abbreviations containing AE are converted to Æ.
I have controlled this by editing the accanthis.sty file to change \defaultfontfeatures to
\defaultfontfeatures{
Ligatures = NoRequired,...
instead of TeX, but this seems like a terrible solution.
How should I change a template to do the same thing? At the moment, it contains
\usepackage{accanthis}
Is there a way of overriding the sty commands in the .tex file and not editing the .sty file?
