Comment (by vegansalad):

 I'm curious which way the TBB community is looking to go from here.

 Does a new font need to be packaged for Linux TBB that renders Dingbats /
 Glyphs / Older Unicode?

 Does it already have a font that renders them properly, but there isn't
 proper font fallbacks in place?

 Are the web and app developers, including uBlock and Trac (see child
 tickets) at fault for including these things in their code? Is it a
 security vulnerability to render old unicode images?

 If the third one is true, we should develop a document that explains the
 secure way to use them or ways to replace them with something else.
