I was actually hoping it could automatically add rules to compose Latin accented characters but there’s no sign of them, is that expected behaviour? For example R + ringbelowcomb + macroncomb, is there a way for Glyphs to write the rules automatically to compose that?
EDIT also to write
sub [i j]' @CombiningTopAccents by [dotlessi dotlessj];
Actually you’re right maybe I don’t need to have a precomposed R̥̄but I like to have it there to be sure it’s going to get composed correctly (in this website font it’s not composing correctly). But certainly for Mcedilla I need a precomposed version as I want it to look different to the components stuck together.
Just realised I used nonstandard names for dotlessi, dotlessj, they should be idotless and jdotless if this is to work.
