gtk.imcontext_simple.IMContextSimple reads compose sequences from the first of the
following files that is found: ~/.config/gtk-4.0/Compose, ~/.XCompose,
/usr/share/X11/locale/$locale/Compose (for locales that have a nontrivial
Compose file). A subset of the file syntax described in the Compose(5)
manual page is supported. Additionally, include "L" loads GTK’s built-in
table of compose sequences rather than the locale-specific one from X11.
If none of these files is found, gtk.imcontext_simple.IMContextSimple uses a built-in table
of compose sequences that is derived from the X11 Compose files.
Note that compose sequences typically start with the Compose_key, which is
often not available as a dedicated key on keyboards. Keyboard layouts may
map this keysym to other keys, such as the right Control key.
gtk.imcontext_simple.IMContextSimple also supports numeric entry of Unicode characters
by typing <kbd>Ctrl</kbd>-<kbd>Shift</kbd>-<kbd>u</kbd>, followed by a
hexadecimal Unicode codepoint.
For example,
Ctrl-Shift-u 1 2 3 Enter
yields U+0123 LATIN SMALL LETTER G WITH CEDILLA, i.e. ģ.
gtk.imcontext_simple.IMContextSimple is an input method supporting table-based input methods.

Dead keys
gtk.imcontext_simple.IMContextSimple supports dead keys. For example, typing
dead_acute a
yields U+00E! LATIN SMALL LETTER_A WITH ACUTE, i.e. á. Note that this depends on the keyboard layout including dead keys.
