I think the relevant issue is whether the editor can render the OpenType ligatures (well, contextual alternates) contained in the font.<p>You _could_ convert to .ttf, changing the curves to  TrueType-style quadratics, but they&#x27;d still have to have the OpenType substitution tables for the &quot;ligatures&quot; to work, and I don&#x27;t think that would really improve compatibility much, if at all.
