Yes, this might work, but I’m afraid I need to disable other default features such as ligatures (not only liga, but TeX ligatures).
I had this problem typesetting XML sources and I didn’t know how to disable the other features. The default setting is “feature=default” and to get expansion/protrusion additional to kerning etc. you have two options:
1. Add them to the default feature with \definefontfeature[default][default][expansion=quality,protrusion=quality] 2. Set multiple feature with \definefontfamily[...][...][...][features={default,quality}] You can use the second method when you want only expansion/protrusion. When you set only “features=quality” kerning isn’t enabled because the default features aren’t applied to your font. Wolfgang
