+++ This bug was initially created as a clone of Bug #2173935 +++

Description of problem:
For Qt applications, Noto Color emoji doesn't get used because the fontconfig definition to set this up doesn't exist.

How reproducible:
Always

Steps to Reproduce:
1. Install any Qt based application with text input
2. Enter in emoji into the text field

Actual results:
The application shows only black and white emoji.

Expected results:
The application shows color emoji.

I don't know if it'd be possible to squeeze this in for RHEL 9.2, but it would be nice if we could, since it's such a small and simple fix.

If any fix is produced it will land in CentOS Stream first and be reflected in a subsequent future RHEL minor release after that.

Comment 5 Jens Petersen 2023-04-04 10:12:54 UTC
Moving this to Qt in line with bug 1954359

(This may also require rebuilding qt5-qtwayland?
 but I guess first an acceptable fix is needed)
