xkbcomp: Add Unicode code point escape sequence \u{NNNN} Unicode code point escape sequences `\u{NNNN}` are replaced with the UTF-8 encoding of their corresponding code point `U+NNNN`, if legal. Supported Unicode code points are in the range `1‥0x10ffff`. Note that we will reject the `U+0000` NULL code point, as we reject it in the octal escape sequence `\0`. This is intended mainly for the upcoming feature to write keysyms as UTF-8 encoded strings. It can be used for various reasons: - avoid encoding issues; - avoid issue with font rendering (e.g. Asian scripts); - make white space or zero-width characters more readable.

libxkbcommon
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 and a separate registry library for listing available keyboard layouts.
Quick Guide
- Introduction to XKB: to learn the essentials of XKB.
- User-configuration: instructions to add a custom layout or option.
- Quick Guide: introduction on how to use this library.
Building
libxkbcommon is built with Meson:
meson setup build meson compile -C build meson test -C build # Run the tests.To build for use with Wayland, you can disable X11 support while still using the X11 keyboard configuration resource files thusly:
meson setup build \ -Denable-x11=false \ -Dxkb-config-root=/usr/share/X11/xkb \ -Dx-locale-root=/usr/share/X11/locale meson compile -C buildComplete list of user options
@include meson_options.txtAPI
While libxkbcommon’s API is somewhat derived from the classic XKB API as found in
X11/extensions/XKB.hand friends, it has been substantially reworked to expose fewer internal details to clients.See the API Documentation.
Dataset
libxkbcommon does not distribute a keyboard layout 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. Further information on xkeyboard-config is available at its homepage and at its repository.
The dataset for Compose is distributed in libX11, as part of the X locale data.
Relation to X11
See Compatibility notes.
