Is anyone working on implementing support for the new OpenType variable fonts in any TeX/LaTeX implementation like XeTeX or LuaTeX? Will fontspec support accessing the new tables?

    It is in harfbuzz 1.4 so I assume it will get into xetex one way or another once xetex gets to that version of harfbuzz github.com/behdad/harfbuzz/releases – David Carlisle Feb 22 '17 at 11:30

    for luatex it's been asked: tug.org/pipermail/luatex/2016-September/006204.html – David Carlisle Feb 22 '17 at 12:43
  • @DavidCarlisle: Note that HarfBuzz is only concerned about the layout part, one still needs to handle generating font instances to be embedded in the PDF, which means xdvipdfmx will need to support that before being able to use variable fonts in XeTeX (same is true for LuaTeX as well). There is also the possibility of an external program creating the instances and being called some how by XeTeX/LuaTeX on demand, then the instances will be used like any other fonts. – Khaled Hosny Feb 28 '17 at 21:32
  • @KhaledHosny true although perhaps we'll be able to tempt "someone" back to fill in the missing pieces:-) (a separate font instance tool sounds like a generally useful thing to have of course, not just for *tex) – David Carlisle Feb 28 '17 at 21:43

    beta version of context supports variable fonts, but it is still experimental. see mailman.ntg.nl/pipermail/ntg-context/2017/088343.html – michal.h21 Apr 23 '17 at 17:52
