I don't know of an easy way. But it's possible to have another primitive that returns the kern at the left resp. right side of a char from such a font.

best would be to have something

\noletterspacekern (will inhibit the next kern) \removeletterspacekern (removes the last kern, a kind of unkern)

so that one can say:

{\fx \noletterspacekern Some Text\removeletterspacekern}

yes it is better to have this. But it's not easy to do (at least for me). Thanh
