As Khaled said on the bug tracker, old style numbers are already available for the text fonts and not important for the math font.
The request for calligraphic is still valid, though.

In version 2.0.0, old style numbers are available via the onum feature and calligraphic by ss01.

Calligraphic (chancery) and roundhand (script) should be made available through the variation selector characters included in Unicode 14.
If I'm not mistaken, U+FE00
corresponds to ss01
and U+FE01
corresponds to ss01
.

U+FE00
corresponds toss01

Already planned as part of issue #218
Confirmed: this is implemented in the font currently in internal beta.
Because the chancery forms are the default in the STIX Two Math font, only the FE01 mappings are needed in the fomat 14 cmap subtable.
The
Thanks @davidmjones I was searching for "calligraphic" in the issues and that didn't come up.
@tiroj On that row 50, Zscript.ss01
is the only one with 0x00fe00
in that image, is that correct?
Good catch! Thank you.
@davidmjones I have fixed this in the sources in the dev repo but you will need to run the build process and update the Fonts folder for testing and before pushing to the public repo.
Old style numbers should be provided by the OpenType feature "onum" on digits.
Calligraphic style should be provided by the OpenType feature "salt" or "ssXX" on "mathematical script" Unicode characters.
