Benefit to Fedora

Noto fonts are actively maintained and have better quality. Users can also have better more consistent experience by using Noto across languages.

Scope

• Proposal owners:
  • Update comps to change the default in @fonts group.
  • Update the priority of fontconfig config in google-noto-fonts package and dejavu-fonts
  • ...

• Other developers:
  • ...

• Release engineering: #Releng issue number (a check of an impact with Release Engineering is needed)
  • List of deliverables: All of the installable images should be affected.

• Policies and guidelines: NO

• Trademark approval: N/A (not needed for this Change)

Upgrade/compatibility impact

Upgrading to f30 for existing users should be unaffected. they will still have DejaVu and so for their default fonts. they can sync up with this change by installing the above list of google-noto-* font packages.

How To Test

Check if the default fonts are same to what the above link of the comparison table describes. try on your locale:

1. fc-match sans-serif
2. fc-match serif
3. fc-match monospace
