@spacekitteh Can you tell a bit about your use case?

@veprbl I knew I forgot something! 😄

I'm using emacs + org-mode, and am using the =unicode-math= package with =stix2-otf= along with lualatex. In order to preview equations, the pipeline goes

emacs makes a standalone document for compiling -> dvilualatex -> dvisvgm -> emacs loads resulting svg

/However/, =dvisvgm= 2.9.1 doesn't understand the extended font data that lualatex emits (see the comments in https://tex.stackexchange.com/questions/537281/using-opentype-font-with-dvilualatex-and-dvisvgm), and so produces corrupt output images. This was fixed in 2.10.1, which was recently released and pushed to CTAN.
