I'm not aware of such an online tool. I've posted a question on
Typedrawers.
http://typedrawers.com/discussion/2292/list-of-opentype-font-feature-inspection-tools At least for the command line I got the right information! Given that many people already have TeXLive installed, the `otfinfo' program is already available and does the right thing. It can also be downloaded separately from https://www.lcdf.org/type/ However, I haven't yet got a point for something that does the same with a GUI or online. https://codereview.appspot.com/328140043/ _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
