Hello, dear list !

In order to fix a few bugs in some OpenType features included in EB Garamond font provided by Google Fonts, I am trying to remove some ligatures (erroneous in some contexts) with fonts.handlers.otf.addfeature.

I must be missing something, because I can't get it to work.

Here is a minimal —non working—example :-)

(The attempted removal (“f_i” → “fi” only before “o”) is of course irrelevant. I chose it just for the sole purpose of this test, to provide a simple example. What I am trying to achieve is more complex, with other ligatures.)

fonts.handlers.otf.addfeature{

        name = "unfio",

        type = "chainsubstitution",

        lookups = {

            { type = "multiple",

            data = { [ "f_i" ] = { "f", "i" } }

            }

        }

        rules = {

            { after = { { "o" } },

            current = { { "f_i" } },

            lookups = { 1 } }

        }

    }

}

Could someone please explain to me what I did wrong ?
