I am not sure how one would (sensibly) use that opentype feature along with a change of axis for a variable font. (Your hesitation for a variable math font is not unwarranted, and might in the end not be something that works) On Fri, Oct 4, 2024 at 9:12 AM Mikael Sundqvist wrote:

PS I hate to say that I am hesitant about a variable opentype math font, but I look forward to be proven wrong.

Hi,

I was wondering if there is a (good) way to have a specific font for

sub/superscripts in mathematics that is different from the main font?

...

I ask because I am working on a variable opentype math font, and it can

be made to look a better if the superscripts are made a little bolder.

Thanks in advance for any suggestions or examples.
