Subject: [RFC] [PATCH] Change default display of variation selectors
Date: Mon, 20 Sep 2021 23:04:10 +0200 [thread overview]
Message-ID: <87a6k7hsc5.fsf@gmail.com> (raw)
etc/TODO says:
*** Consider changing the default display of Variation Selectors
Attached a patch to use 'zero-width for them by default (since theyʼre
frigging annoying). We could use 'thin-space by default I suppose. Do
we need to support VS-16 through VS-32 as well?
Robert
