+Subject: [PATCH] conf: Prefer system emoji fonts to third-party ones
+
+Prefer the system provided emoji fonts on systems which provide one,
+such as Windows, MacOS and Android, even if the Emoji One or Emoji Two
+fonts are installed.
+
+This also allows free software OSes such as GNOME to prefer the Emoji
+One font, which is not used in other OSes and therefore has a unique
+brand identity, by installing them and only them by default.
+
+Users can use more capable fonts while Emoji One and Emoji Two catch up
+by installing a font otherwise already used by another system, such as
+Google's freely redistributable Noto Emoji font.
