# 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:
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
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.
