Bundled emoji font
NotoColorEmoji.ttf reports Noto Color Emoji version 2.051 and covers
Unicode Emoji 17.0. It is vendored from Debian's
fonts-noto-color-emoji 2.051 package, built from the corresponding
Google Noto Emoji release.
By default, GTK builds install this exact file, including Windows
(installer and portable builds), AppImage, Flatpak, and native Meson/RPM.
Meson packagers can set -Dinstall-emoji-font=false to omit the bundled
font and its installed notices and use system emoji fonts instead. An
explicit ZOITECHAT_EMOJI_FONT path still enables the private font map
in such builds. With the bundled font, it is registered privately as
ZoiteChat Emoji; an older system Noto font cannot replace it. No font
is installed globally on Windows.
Chat windows and the emoji picker share this map. Fontconfig still loads
system fonts and configuration for ordinary text, and the configured text
font, size and style remain in effect. In particular, plain digits, #
and * are not assigned emoji metrics.
Windows uses the same FreeType backend rather than GDI registration or an OS-version-specific picker. The dependency bundle already ships FreeType, Fontconfig and PangoFT2. This rendering path does not require Windows' native color-font support. Actual Windows 7 execution still needs testing on that OS.
Meson requires PangoFT2 >= 1.44 and Fontconfig >= 2.13. Normal installations
load share/fonts/zoitechat/NotoColorEmoji.ttf beneath the configured data
directory; Windows resolves it relative to the executable. AppImage sets
ZOITECHAT_EMOJI_FONT to its own copy. For an uninstalled development build:
ZOITECHAT_EMOJI_FONT="$PWD/data/fonts/NotoColorEmoji.ttf" build/src/fe-gtk/zoitechat
An unexpectedly missing or unloadable bundled font logs a warning and retains
system-font fallback. When installation is disabled deliberately, fallback is
quiet unless an explicit ZOITECHAT_EMOJI_FONT override is invalid.
CI verifies the installed copy and tests catalog/font coverage; AppImage and
Windows also run the interactive picker regression tests. Native themes,
DPI and different Pango/Cairo versions can still affect pixel-level output.
