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.

Every GTK build installs this exact file: Windows (installer and portable build files), AppImage, Flatpak and native Meson/RPM builds. It is loaded into a private Pango/FreeType font map 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

A missing/unloadable file logs a warning and retains system-font fallback. 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.
