I'm typesetting some proceedings which include a good number of

The trouble is that excessive space is often introduced between the

bracket and the punctuation. I can control the excessive space that

sometimes occurs between ) and . by using )\periods[1], although this

ruins the protrusion if it occurs at the end of a line.

Does anyone know how I might be able to somehow "tie" ) to . , ; : so

that the distance remains reasonable, and so that protrusion still

works?

you first have to make an MWE that demonstrates how protrusion works 

here ... then we can see how we can best deal with it

Anyway, often tricks for this can be found in the test suite of font 

manual(s) ... here is a variant ...

\startluacode

     fonts.handlers.otf.addfeature {

         name     = "mykerns",

         type     = "kern",

         data     = {

             [")"] = {

                 [","] = -300,

                 ["."] = -300,

                 [":"] = -250,

                 [";"] = -250,

                 [")"] = -100,

             },

         },

     }

\stopluacode

\definefontfeature[default][default][mykerns=true]

\setupbodyfont [dejavu,12pt]

\startTEXpage[offset=10pt]
