Font fallback works on KDE 5.27 though (on a brand new Debian 12 installation). I posted on KDE forum about this a while ago ([link](https://discuss.kde.org/t/kde-6-no-fallback-font-on-konsole-and-other-applications-fedora-40/14719)). Not sure which application is responsible to this bug. STEPS TO REPRODUCE (Note: This is how you reproduce it in Konsole) 1. Download `NerdFontsSymbolsOnly.tar.xz` from [ryanoasis/nerd-fonts](https://github.com/ryanoasis/nerd-fonts/releases), then unzip it and move it to `$HOME/.local/share/fonts`, then run `fc-cache -f`. Close all instances of Konsole afterwards 2. Open a new instance of Konsole. Go to [Nerd Font cheatsheet](https://www.nerdfonts.com/cheat-sheet) and search for a random nerd font symbol (e.g. `nf-fa-fedora`), then copy the `Icon` (not `Class` or `UTF`) variant and paste it to Konsole. Notice that it just displays a square. 3. Go to Konsole settings, create a new profile that uses `Symbol Nerd Font Mono` as font. Then create a new Konsole window with this profile and paste the nerd font symbol again. The symbol is displayed correctly in this case. OBSERVED RESULT A square is displayed in place of the nerd font if my current font is not `Symbol Nerd Font Mono` EXPECTED RESULT The nerd font symbol is correctly displayed regardless of my current font (as long as I installed nerd font correctly) SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 6.0.80 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.0 Kernel Version: 6.5.0-28-generic (64-bit) Graphics Platform: Wayland Processors: 4 × AMD Ryzen 9 5900X 12-Core Processor Memory: 3.8 GiB of RAM Graphics Processor: llvmpipe Manufacturer: QEMU Product Name: Standard PC (Q35 + ICH9, 2009) System Version: pc-q35-7.2 ADDITIONAL INFORMATION I originally found this issue in a brand new Fedora 40 installation. On a brand new Debian 12 installation, font fallback works after you put the nerd font in `$HOME/.local/share/fonts` and run `fc-cache -f`.
