            Bug ID: 27889
           Summary: pick up font-indicated default ligatures without
                    having to specify liga=1
           Product: CSS
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Fonts
          Assignee: jdaggett@mozilla.com
          Reporter: pomax@nihongoresources.com
        QA Contact: public-css-bugzilla@w3.org

In fonts that come with default ligatures that should simply always be turned
on, it seems counter-roductive to require that the "liga" feature be enabled in
CSS as well. The expectation would be that those ligatures "just work", because
the font indicates this always.

Smallest demonstrator I have is the font used in
http://pomax.github.io/CFF-glyphlet-fonts/, which has a default GSUB ligature
to replace '~', as well as the string 'custom', neither of which work without
explicitly turning on the liga opentype feature in CSS.
