Comment (by vegansalad):

 @yawning Thanks for the clarification. I was using
 https://arthuredelstein.github.io/tordemos/enumerate-fonts.html to get a
 master list of fonts that TBB ships and didn't see NotoEmoji-Regular.ttf
 on the list, but I don't think that page checks for it.

 I saw that someone else filed a ticket
 https://trac.torproject.org/projects/tor/ticket/18364 about dingbats not
 working. You can see a good example of the problem here:
 http://danshort.com/HTMLentities/index.php?w=dingb

 Actually, an even better example is happening right on this page. I'm not
 able to view the "bold" "italic" "link" or any other icons above the box
 that I'm typing in. Also, another person pointed out that the "reply to
 comment" icon to the right of every comment on this page is blank.
 https://trac.torproject.org/projects/tor/ticket/18860

 Dingbats are broken in TBB on Linux and it isn't a fringe issue because it
 is happening on our very own Tracker.
