not surprise, could be that I am testing a local version not yet pushed.
For this reason is better to have a minimal and complete example, otherwise
we waste time .
With my local version
\directlua{
callback.register('kerning', node.kerning)
font.current(font.define{
name = "dummy",
type = "virtual",
characters = {
{
width = 655360,
height = 655360,
depth = 655360,
commands = {{"right", 0}},
},
right_boundary = {
width = 655360,
height = 655360,
depth = 655360,
},
},
})
}
\char1
\bye
$ luatex --fmt=luatex-plain test-tail.tex
doesn't complain .
