Translations:Using Fcitx 5 on Wayland/15/en

For GTK_IM_MODULE, as for now, the modern Gtk 3/4 application should be able to use text-input-v3 which is supported almost by every compositor, except weston. There are a few different options in terms of setting the value of GTK_IM_MODULE. When it is unset, the Gtk built-in Wayland im module will be used for Gtk3 and Gtk4. While you can also enforce it by doing GTK_IM_MODULE=wayland, remember it will be also picked up by Gtk2. Setting GTK_IM_MODULE=fcitx can still work, and it is necessary if your compositor does not support Wayland input method frontend.
