Hoefler Text Pro when put under Style = Historic
will load the long S in, but it is not contextual. It will show up even at the end of words
I've also tried every single Contextual feature available in Fontspec's documentation, no luck so far. Anyway here's the code I'm having issues with
\documentclass{article}
\usepackage{fontspec, xltxtra}
\setmainfont[Style = Historic, Contextuals = {WordInitial, Alternate}]{Hoefler Text Pro}
\begin{document}
sometimes st ct ff ffi ffj fj
\end{document}
The Hoefler Text Pro I have is version 1.201
