I am currently working on a non-script typeface but with several unconventional ligatures. I would like to limit the number of ligatures per word according to their length, in order to keep a fluid rhythm.
I haven’t found a tutorial on this, or one that would fit?
They do not connect? Perhaps a solution with contextual alternates may work for you then. In its most basic form, let’s take a ligature in the shape of two letters stacked on top of each other:
sub @default' @default by @top;
sub @top @default' by @bottom;
The top group would have the top glyph of the ligature, etc. From there it can quickly become more complex, because you will not only have one kind of ligature, and different contexts, etc.
