Then there is the question of scale and move (up/down).
This issue shows up with the STIX and STIX2 fonts, as the former has the superscript digits ¹ ² ³, but not the other which came to Unicode later in a different range.
Although I have some experiemntal (font) magic on my computer it will probably take till next year before it will show up in a beta.
I use the code below, which seems fine, as the two fonts are close to each other. But it seems that one cannot add [force=yes] to ensure they all come from the same font as on the command \definefontfallback. This command would otherwise be good to pick replacements for certain glyphs. \definefallbackfamily [mainface] [serif] [stixtwotext] [range={00B2-00B3,00B9,02070-0208F}] \definefallbackfamily [mainface] [mono] [stixtwotext] [range={00B2-00B3,00B9,02070-0208F}] \definefallbackfamily [mainface] [math] [stixtwomath] [range={00B2-00B3,00B9,02070-0208F}] \definefontfamily [mainface] [serif] [stix] \definefontfamily [mainface] [mono] [stix] \definefontfamily [mainface] [math] [stix]
