excepted for script and italic use, I’m asking myself why not putting something like
sub f' [b h k thorn] by f.short;
directly into a Liga feature if I want it to be active by default of course.
Or to put it into Dlig for
sub f' [ b h k thorn] by f.dlig;
assuming f.dlig has a different letterform than /f/ and /f.short/
If I should put it into Calt instead, what would be the reason to it?
Thanks in advance.
Contextual Alternate VS Liga or Dlig
