After digging in a hidden Reddit comment that suggests I search for “cn” in fcitx5-configtool rather than “Chinese”, a “Pinyin” option occurs under “简体中文”:
This finally makes the pinyin menu work.
My complete setup is like this:
# import this into configuration.nix
{ config, pkgs, ... }:
{
i18n.inputMethod = {
enabled = "fcitx5";
fcitx5.addons = with pkgs; [
fcitx5-gtk
fcitx5-chinese-addons
fcitx5-nord
];
};
}
Additionally,
# ~/.config/fcitx5/conf/classicui.conf
Theme=Nord-Dark
Font="Meslo 28" # Where's my glasses?
