Is there a way to use the upright integral symbol from the recently released Stix Two Math font? Probably a solution, if there is one, would require the package unicode-math and xelatex or lualatex. That'd be OK.

There's not yet a STIX Two distribution for pdflatex, so you need XeLaTeX and LuaLaTeX with unicode-math.

According to the specs, the upright integrals are obtained via ss08:


\setmainfont{STIX Two Text}
\setmathfont{STIX Two Math}[StylisticSet=08]


\int \iint \iiint \oint

Without the option, we get

  • Thank you, this solves my problem. In case I need similar info: where is this "specs" located (link, document name, etc.)?

  • @balcinus The downloaded ZIP file contains a docs folder with STIX_2.0.0_stylistic_sets.pdf inside it.
