Thanks, let's dupe to bug 151057 as it is the root issue in this particular
case.

Downgrading to google-noto-color-emoji-fonts-20241008-2.fc42 does fix the
issue.

Newer version of the packge uses COLRv1, according to the changelog. So it's
really is a bug #168412.

In Fedora 42, the font inside PDF file contains images (XObjects of type Image)
of emojis, however in Fedora 43 it's just a font, which I can't properly open
in any font application (fontforge segfaults, https://opentype.js.org/ shows
nonsense).

Downgrading google-noto-color-emoji-fonts did not fix the issue.

This was discussed in the dev chat and while fontconfig is the likely root
cause, LibreOffice should do better.

I'm interested in hearing

- what is the result with 25.8 on Fedora 42
- what is the result with 25.2 on Fedora 43

Guided by those results, you could do bibisecting per what I said in comment 3

Just now I tested 25.8 in a Fedora 42 distrobox container, but did not see the
issue.

Downgraded LO to 25.8.1.1-0.2.fc43 on Fedora 43, no changes, still blank
character. So it's not a LO, probably fontconfig/freetype?

> If you indeed do not see the issue in 25.2

I've tested it just now in Docker containers of the distros, with

soffice --convert-to 'pdf:draw_pdf_Export' printer.odt

Just re-tested it with google-noto-color-emoji-fonts installed.

Arch (libreoffice-fresh 25.8.4-3): no changes, tofu character
Fedora 42 (LO 25.2.7.2-1.fc42): OK proper rendering
Fedora 43 (LO 25.8.4.2-2.fc43): blank
Ubuntu 26.04 (LO 25.8.4~rc2-0ubuntu1): OK proper rendering


I don't know how to check which font is used for the exact emoji. Something
with fc-query?

Works fine here.

If you indeed do not see the issue in 25.2, you could bibisect it with the 25.8
repository:
https://wiki.documentfoundation.org/QA/Bibisect
https://wiki.documentfoundation.org/QA/Bibisect/Linux

I recommend Fedora or Ubuntu as Arch might have issues running the builds.

Arch Linux 64-bit
Version: 25.8.4.2 (X86_64) / LibreOffice Community
Build ID: 580(Build:2)
CPU threads: 8; OS: Linux 6.18; UI render: default; VCL: kf6 (cairo+wayland)
Locale: fi-FI (fi_FI.UTF-8); UI: en-US
25.8.4-1
Calc: CL threaded
