How do I use the fonts?

[Oak-Trees]

I'm using Raspberry Pi OS Bookworm.

How do I define a font in the config.conf? All I'm getting are hollow squares as fonts.
I installed the fonts in /usr/share/fonts and ~.local\share\fonts but nothing works.

I ran into this problem myself, many of these themes are several years old, and I found some of the mentioned fonts have changed their icon sets.

As mentioned in the links below

With Release v3.0.0 the Material Design Icons were updated and moved to new codepoints (reasons for that are in the release notes).
They are still shown here for reference, but are missing in the actual fonts.
To find for example the replacement for nf-mdi-altimeter enter just altimeter in the search box.

My solution was to use one of the nerd/hack fonts

Then replace all the symbols ion the config file, one by one with the symbols found there, which you can look up easily - https://www.nerdfonts.com/cheat-sheet

It's tedious, but it will work, until someone either updates the configs, or comes up with a more elegant solution.

I'm pretty sure the configs still work just fine because I tested them out myself right now with ttf-material-design-icons-extended and Fira Code Nerd Font and everything seems to be fine, is this still a problem which is happening
