Description Deron Meranda 2012-08-27 02:37:33 EDT
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):

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.
Comment 2 Pravin Satpute 2012-10-05 01:02:25 EDT
closing, please reopen if required.
Comment 3 Krasnaya Ploshchad’ 2017-06-23 00:32:12 EDT
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.
