Confession time: I haven’t had a working LuaTeX since I moved everything to a newer computer and only just managed to install a pretest TeX Live 2014. I can now see what the problem is: there has been a change in XeTeX’s maths handling so that remapping back to ascii for class 7 glyphs is indeed necessary after all. I have to admit I was extremely surprised when it worked the other day without the remapping. > As posted the second display headed by "Roman, italic, and bold math families:" > made three blocks of coloured missing glyph markers. Was that expected? No — it worked in TeX Live 2013, but not in 2014 :) * * * I’ve attached a now-working example below; it also runs in plain LuaTeX but for some reason the colours don’t show up in maths. Hope this helps, Will
