xkbcommon-compose.h: change recommended locale fallback code to treat empty string same as unset The previous code would cause failures to find the Compose file if one of the environment variables LC_ALL, LC_CTYPE or LANG are set to the empty string. The description of the fallback procedure in loclale(7) talks about "non-null environment variable"; I interpreted this to mean the environment variable is unset, but it actually means unset or empty (I verified this by looking at what glibc and musl do). A recent bug in systemd https://github.com/systemd/systemd/issues/6407 exposed this issue. It causes these these variables to be set to the empty string in TTY sessions.

libxkbcommon is a keyboard keymap compiler and support library which processes a reduced subset of keymaps as defined by the XKB (X Keyboard Extension) specification. It also contains a module for handling Compose and dead keys.
See Quick Guide.
libxkbcommon is built with Meson:
meson build
ninja -C build
To build for use with Wayland, you can disable X11 support while still using the X11 keyboard configuration resource files thusly:
meson build \
-Denable-x11=false \
-Dxkb-config-root=/usr/share/X11/xkb \
-Dx-locale-root=/usr/share/X11/locale
ninja -C build
While libxkbcommon’s API is somewhat derived from the classic XKB API as found in X11/extensions/XKB.h and friends, it has been substantially reworked to expose fewer internal details to clients.
See the API Documentation.
libxkbcommon does not distribute a keymap dataset itself, other than for testing purposes. The most common dataset is xkeyboard-config, which is used by all current distributions for their X11 XKB data. More information on xkeyboard-config is available here:
http://www.freedesktop.org/wiki/Software/XKeyboardConfig
The dataset for Compose is distributed in libX11, as part of the X locale data.
See Compatibility notes.
