+/// You can explore them all in the Font Book in [the online demo](https://emilk.github.io/egui/).
+///
+/// In addition, egui supports a few special emojis that are not part of the unicode standard.
+/// This module contains some of them:

+    /// Tux, the Linux penguin.
+    pub const OS_LINUX: char = '🐧';
+    /// The Windows logo.
+    pub const OS_WINDOWS: char = '';

+    pub const OS_ANDROID: char = '';
+    /// The Apple logo.
+    pub const OS_APPLE: char = '';
+
+    /// The Github logo.
+    pub const GITHUB: char = '';
+
+    /// The word `git`.
+    pub const GIT: char = '';
