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
