    /// ## Compose sequences
    ///
    /// [`IMContextSimple`][crate::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). The syntax of these files is described in the Compose(5)
    /// manual page.
    ///
    /// If none of these files is found, [`IMContextSimple`][crate::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.
    ///
    /// ## Unicode characters
    ///
    /// [`IMContextSimple`][crate::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.
    ///
    /// ## Dead keys
    ///
    /// [`IMContextSimple`][crate::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
