Cannot export font with substitution code in ccmp for runic letters


The glyphs are set to export and Glyphs reports no errors in the the feature section. Issues only appear when you try to export them.

The code is a simple substitution test for ligatures and variant forms using zero width joiners and variant selectors.

sub o-runic zerowidthjoiner kaunK-runic by _o_k.runic;
sub o-runic VS1 by o-runic.reversed;
sub o-runic VS2 by o-runic.inverted;
sub o-runic VS3 by o-runic.turned;

Do you have a custom parameter that removes those glyphs from the exported instance?

I forgot to turn that off, thanks.
