Re: [Bug-gnuzilla] Emoji in IceCat

Mart,

Well, as much as I hate to say it, there's nothing to show.

I modified the following about:config settings:

  * font.name.monospace.x-unicode
  * font.name.monospace.x-western
  * font.name.sans-serif.x-unicode
  * font.name.sans-serif.x-western
  * font.name.serif.x-unicode
  * font.name.serif.x-western

After replacing Noto Emoji in those settings with any of the font names
that made sense to me ("Twemoji" and "Twemoji Mozilla") as well as the
PostScript name ("TwemojiMozilla", according to fc-query), I was left
with no Emoji at all, at least on the Wikipedia page that you were
referring to before [1].

Restarting IceCat didn't result in any changes.

At the time of testing, `fc-list` (both the Guix and standard one)
included the Twemoji font after I had put the .ttf file into
.local/share/fonts and refreshed the font cache with `fc-cache -vf`.

Apparently, this is either because I'm too dumb and did something wrong
while testing or IceCat is unable to handle colour emoji fonts in
general.

Do you know if there's any way to check if IceCat encounters any errors
while trying to load fonts that are specified in about:config?
