[edit] Detailed Description

Liberation fonts is one of the important font in Fedora distribution.

  • Provides metric compatibility with Arial, Times New Roman, and Courier New fonts of Microsoft Windows platform.
  • Default fonts in Libre Office.

Issues:

  • Existing License of liberation fonts is complex.
  • Over the last couple of years we have RFE's to increase coverage of Liberation fonts to support more scripts.
    • "RFE: Add Greek Polytonic support to Liberation fonts" #473842
    • "Serbian glyphs for Wikipedia" #657849
  • We are noticing some tricky Hinting issues. #591554, #591556, #606217 #768067, #768067

Solution:

  • Upstream latest release 2.00.0 based on google croscore fonts resolves all these issues.

[edit] Benefit to Fedora

  • Liberation fonts-2.00.0 is as per Fedora project recommended OFL license.
  • Provide more character covarage.
    • Latest Version - Older Version
    • 2302 (sans) - 667
    • 2274 (mono) - 666
    • 2303 (serif) - 662
  • It provides support for Greek Polytonic characters. Bug open for this as a RFE.
  • Improved hinting.

[edit] Scope

  • Upstream release based on croscore fonts.
  • Package liberation-narrow-sans as a different package in Fedora. Since licensing issues still not fixed for Liberation Sans Narrow
  • Build latest liberation fonts 2.00.0 for Rawhide
  • Testing and bugfixing

[edit] How To Test

  • Install liberation fonts 2.00.0 version
  • Observe differences from earlier version.
  • Check rendering of your test in Libre Office.
