Hi Hans,

in the old loader, defining a feature containing mixed ligature / substitution causes a crash. Here’s an example:

 \enabletrackers [otf.loading]
 \startluacode
   fonts.handlers.otf.addfeature ("dunno", {
       {
           type      = "substitution",
           data      = { [0x0022] = 0x201D },
           prepend   = true,
       },
       {
           type     = "ligature",
           data     = { [0x2013] = {0x002D, 0x002D} },
           prepend  = true,
       },
   })
   fonts.handlers.otf.features.register {
       name        = "dunno",
       description = "bug demo",
   }
 \stopluacode

 \definefontfeature [myfeat] [default] [dunno=yes,liga=yes,mode=node]

 \definefont [somefont] [file:cmunrm.otf*myfeat]
 \starttext
   \somefont foo bar " baz
 \stoptext

This crashes in font-otn on account of a number being indexed. This used to work -- anything that can be done about it?

i'll see if i can fix it but don't expect all upcoming features in the new loader to work in the old one

Hans
