Description
The rendering of package README.md files on the Typst Universe site uses Cascadia Mono to render code blocks. Unfortunately the site seems to be useing a webfont version of this font with a limited subset of characters available. According to the CSS, the font itself is is served from https://typst.app/assets/fonts/CascadiaMono-Regular-Sub.woff2.
This font seems to have been subsetted in such a way that it does not have the characters needed to render Turkish properly. I checked some French and German packages I found with non ASCII characters inside code blocks in their README.md files and they seemed fine, e.g. I confirmed that [öğçüé] and others were fine. Missing seem to be at least [ıİşŞğĞ]. This makes for some very sub-par rendering of my decasify package:
Given that many other diacritics are supported and the upstream font has support for Turkish, I would like to request a new subset be generated with more complete coverage, possibly without any language subset optimizations at all so that future language additions don't run into the same problem.
