List of google-noto-*-fonts packages with Appstream data issues

Description of problem:

Many international google-noto-*-fonts have invalid Appstream data. This causes warnings in applications using Appstream, like KDE Discover. It also makes many appstreamcli commands not work.

Version-Release number of selected component (if applicable):

Most of them are version 20181223-8.fc33

How reproducible:

Should be easy

Steps to Reproduce:

1. sudo dnf install google-noto-sans-arabic fonts (I will attach a txt file with the full list of google-noto fonts with this issue)

Actual results:

Running `appstreamcli status` warns "Error while loading the metadata pool: Many components have been recognized as invalid. See debug output for details." Verbose output with `appstreamcli status --verbose` is attached in txt file.

Opening KDE Discover creates a warning that "Please make sure that Appstream is properly set up on your system".

Expected results:

Running `appstreamcli status` reports no errors. Opening KDE Discover shows no warning.

Additional info:

Removing the specified fonts fixes the issues. I tried force refreshing appstream cache, rebooting, reinstalling appstream data, etc.

TXT file with list of the violating fonts is attached.
