Is it worthwhile to put combining mark anchors in letters like ð, ß, ŋ? Are there enough mad linguists out there that a commaaccent will inevitable end up under a capital eszett? Does this stuff add so much bloat to web fonts that it might delay a user from loading two dozen tracking scripts by a millisecond? I don’t see an obvious reason to set this stuff up. But the Brill fonts can handle any crazy thing I throw at them (except y+ogonek, that looks gross) so I worry that there really is someone who needs every crazy possibility to work.
