A brief note for Fcitx5 as the Korean Input Method in Debian Sid + Wayland + Sway

For more details: https://fcitx-im.org/wiki/Using_Fcitx_5_on_Wayland

Steps

Install packages:

$ sudo apt install -y \
    fcitx5 \
    fcitx5-config-qt \
    fcitx5-hangul \
    qt5ct

# If need
$ sudo apt install -y \
        fonts-nanum \
        fonts-nanum-coding \
        fonts-noto-cjk 

Configure the env variables:

$ sudo vi /etc/environment # or ~/.profile

export GTK_IM_MODULE=fcitx # fcitx5 might show a warning if enable, but should be enabled for Chrome.
export QT_IM_MODULE=fcitx
export XMODIFIERS=@im=fcitx
export GLFW_IM_MODULE=ibus
export SDL_IM_MODULE=fcitx
export QT_SCALE_FACTOR=2 # for 4k monitors
export QT_QPA_PLATFORMTHEME=qt5ct

Add the fcitx daemon and Chrome launching parameters in the sway config:

$ vi ~/.config/sway/config

exec --no-startup-id fcitx5 -d
bindsym $mod+y exec google-chrome-stable --enable-features=UserOzonePlatform --ozone-platform=wayland --gtk-version=4 --enable-wayland-ime 

Update Chrome flags:

1. Launch Chrome
2. Open the flags page - chrome://flags
3. Search for Preferred Ozone platform and configure it as Wayland
