fyi: the number changes because a non-char node is checked (so it then

done right (advanced otf kerning)
Ah, so do you mean the fix will be not to make this check in the cases
that the node is not a char node?
$f_x$ char
$f_\hbox{x}$ box
$f_{x+1}$ mlist
we need to identify the first and third case as valid candidates for
kerning and the inspection code had a flaw triggered by the hbox
