[Question] material symbols extension

[o-murphy]

I made a simple extension called QtMDi for QtAwesome to allow usage of google official material design iconic fonts

Now it takes official .woff2 fonts from material-symbol npm package convert it to .ttf using GitHub workflow

I want to implement fully automatic updates to the latest fonts version

Now I have a few issues, maybe you can help me with it

1. Now the fonts loads dynamically from .ttf files. Is there are the way to make that using the .qrc?

2. I use the Google/woff2 (woff2_decompress) tool to convert .woff2 to .ttf. It has the issue, the glyphs that have been filled in .woff2, are not that in .ttf and I can't find a way to make them look as expected

3. I use the specific fonts for apply styles (outlined/rounded/sharp) and weight (100-700) for glyphs. Also we can use QSize to set optical size. But I can't find a way to apply FILL and GRADE properties which allows by web fonts in .woff2 format

4. The libraries that uses .woff2 fonts apply the properties as GRADE, FILL, etc. through the .css stylesheets. Are there the way to do it in QtAwesome or is there the alternative e.g. via .qss (I know it supports something like font-face) or some other methods?
