Hi
i have an arabic font(without Latin section) with very low space width, this affects the space width of the fallback Latin font, so i wrote a locl feature like this:
lookup locl_0 {
sub space by space.Latin;
} locl_0;
script latn;
lookup locl_0;
but Glyphs include the arab
script in final font:
feature locl {
script DFLT;
language dflt;
lookup SUB_2 {
sub space by uniE00B;
} SUB_2;
script arab;
language dflt;
lookup SUB_2;
script latn;
language dflt;
lookup SUB_2;
} locl;
