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. 117475 1 jdaggett 2015-01-26 00:43:35 +0000 Hi Mike, The mechanism by which ligatures "just work" is that OpenType defines a set of features that should be applied by default, which is precisely what good layout applications do. The wording of the CSS3 Fonts spec is that user agents should apply these default features to all text. Currently only Firefox does this but I expect Chrome will at some point switch to doing this also. So I don't think there's anything here that's a spec bug per se, you should be filing bugs against Chrome and Webkit since they don't implement default feature support (it needs to be enabled explictly or via 'text-rendering: optimizeLegibility').
