And that `include "%L"` does something different as introduced in
3b4b1c6878
Note that user can still use `include "/.%L"` as a workaround.

/**
|
||
* GtkIMContextSimple:
|
||
*
|
||
* `GtkIMContextSimple` is an input method supporting table-based input methods.
|
||
*
|
||
* ## Compose sequences
|
||
*
|
||
* `GtkIMContextSimple` 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, `GtkIMContextSimple` 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.
|
||
*
|
||
* ## Unicode characters
|
||
*
|
||
* `GtkIMContextSimple` 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.
|
||
*
|
||
* ## Dead keys
|
||
*
|
||
* `GtkIMContextSimple` 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.
