           Summary: Latin ligatures need 'liga' standard ligature lookups
        Regression: ---
      Story Points: ---
    Classification: Fedora
                OS: All
          Reporter: [e-mail]
              Type: Bug
     Documentation: ---
          Hardware: All
        Mount Type: ---
            Status: NEW
         Component: liberation-fonts
           Product: Fedora

Description of problem:
Glyphs in the Latin Ligature block (U+FB00 .. U+FB06), such as "fi" and "fl",
should have the OpenType 'liga' lookup features defined. That will allow text
renderers to automatically apply the ligature glyph.

Additionally, for completeness, the ligature caret horizontal positions should
be appropriately set for these glyphs.

Version-Release number of selected component (if applicable):
liberation-fonts-2.00.0

Additional info:
You may need to solve bug #851790 first.

Also the "fi" (and "ffi" if existing) should exclude dotless-i
scripts/languages, e.g., Turkish.

Yes, we can enable it.
But i think enabling it will loose metric compatibility with Times New Roman
and Arial.

In Windows 10 Times New Roman and Arial does not has 'liga' feature for ff, fi,
fl, tz and so on, they using 'dlig' feature instead.
