  • I am unable to reproduce the issue you've encountered on my up-to-date MacTeX2018 distribution under LuaLaTeX. I.e., I get the swashy z and the one-storey g in text, script, and scriptscript mode. Please tell us which document class you employ, which TeX engine you employ, and which version of the Stix Two fonts you employ.

    It probably depends on the order of the feature lookups in the font, if ssty (activated by default for script and scriptscript fonts) precedes ss02 then ss02 will have no effect. Checking the font, this is indeed the case, so I think the issue should be reported in github.com/stipub/stixfonts/issues.

This looks like a bug to me, and I haven’t tried to determine whether it’s in unicode-math or in XeTeX. Here is a temporary workaround:



setmathfont{STIX Two Math}[StylisticSet=2,
script-features={},
sscript-features={}]


Sample of workaround



Setting StylisticSet=2 inside script-features does not currently work. You might limit the scope of the workaround by loading it with range=. as in:



setmathfont{STIX Two Math}[StylisticSet=2]
setmathfont{STIX Two Math}[StylisticSet=2,
range=it/{latin},
script-features={},
sscript-features={}]


Setting the range to only the individual letters that need it does not work, either.



Since only XeTeX currently needs it, you might wrap it in ifXeTeX from the iftex package. That would give you:



documentclass[varwidth, preview]{standalone}
usepackage{iftex}
usepackage{amsmath}
usepackage{unicode-math}

defaultfontfeatures{ Scale = MatchLowercase }
setmainfont{STIX2Text}[
Scale = 1.0 ,
Ligatures = {Common, TeX},
UprightFont = *-Regular ,
BoldFont = *-Bold ,
ItalicFont = *-Italic ,
BoldItalicFont = *-BoldItalic ,
Extension = .otf ]
setmathfont{STIX2Math.otf}[StylisticSet=2]

ifXeTeX
setmathfont{STIX2Math.otf}[StylisticSet=2,
range=it/{latin},
script-features={},
sscript-features={}]
fi% XeTeX

begin{document}
$g^g_{g^g}$ $z^z_{z^z}$ $alpha^alpha_{alpha^alpha}$
end{document}

  • I don't think that it is a good idea to disable the script features. Try e.g. $x^{2a+b^2}$ with and without them.

  • @UlrikeFischer I agree that it’s suboptimal, but that’s the workaround I found. The second workaround at least preserves the script features of 2, capitals and the Greek letters. Do you have a better one? Other than using LuaLaTeX?
