Enabling stylistic sets

Enabling stylistic sets

[Karan Ahlawat]

Is there any way to enable stylistic sets in Emacs?

I have set the fontfeatures I want enabled in a fontconfig configuration 
file. It works everywhere else, but Emacs. Now, seeing as how 
ligature.el is able to leverage Emacs built with Harfbuzz for enabling 
ligatures, is there some  way to enable stylistic sets as well?


Thanks,

Karan

Emacs doesn't (yet) support stylistic sets.  There's a TODO item to
add this, with some initial ideas, so patches are welcome.  (One of
the aspects of this which needs to be figured out up front is how to
let Lisp programs and users tell Emacs when to use what stylistic sets
and what set to use for which parts of text; ideas and proposals are
welcome.)
