Hi, I really like the idea of using a single font and only changing variables and using it for the whole document. Ubuntu Sans (Variable) makes this possible, but upper diacritics (eg. Ä) are not scaled when width is changed, the lower diacritics (eg. ą) seem to work as desired. Unfortunately, I can't narrow down the problem any further. I can change the width with Google Fonts without any errors, and Inkscape doesn't cause any problems either. How can I fix that?
