My motivation for writing this patch is that I wanted to continue to use the settings in the following file after switching to Guix Home. https://git.sr.ht/~taiju/taix/tree/31a37c231ebba60e38f7fa9cfe1c7a5d7362d021= /item/dotfiles/fontconfig/.config/fontconfig/fonts.conf Honestly, I don't know why it is so complicated, but I refered it from the following ArchWiki content. https://wiki.archlinux.org/title/Font_configuration/Examples#Japanese Therefore, just being able to set font aliasing is unfortunately not enough to satisfy my use case. Thanks, -- Taiju
