* Compose file). The syntax of these files is described in the Compose(5)
* manual page.
*
+ * ## Unicode characters
+ *
* GtkIMContextSimple also supports numeric entry of Unicode characters
* by typing Ctrl-Shift-u, 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.
+ *
+ * ## Emoji
+ *
+ * GtkIMContextSimple also supports entry of Emoji by their name.
+ * This works by first typing Ctrl-Shift-e, followed by an Emoji name.
+ *
+ * The following names are supported:
+ * - :-) 🙂
+ * - 8-) 😍
+ * - <3 ❤
+ * - kiss 💋
+ * - grin 😁
+ * - joy 😂
+ * - :-* 😚
+ * - xD 😆
+ * - like 👍
+ * - dislike 👎
+ * - up 👆
+ * - v ✌
+ * - ok 👌
+ * - B-) 😎
+ * - ;-) 😉
+ * - ;-P 😜
+ * - :-p 😋
+ * - 3( 😔
+ * - :-( 😞
+ * - :] 😏
+ * - :'( 😢
+ * - :_( 😭
+ * - :(( 😩
+ * - :o 😨
+ * - :| 😐
+ * - 3-) 😌
+ * - >( 😠
+ * - >(( 😡
+ * - O:) 😇
+ * - ;o 😰
+ * - 8| 😳
+ * - 8o 😲
+ * - :X 😷
+ * - }:) 😈
