Hi,

I've search about this issue and found the following link:
https://old.reddit.com/r/openbsd/comments/1atanzd/color_emoji_not_shown/

When I apply the recipe describe by sthen@ here, I can make color emoji
to work in Emacs (and probably other applications).  Therefore, I
propose that we add the following patch to etc/PROBLEMS.  WDYT?

 The only workaround is not to choose such font variants as the default
