Patch Homepage: https://st.suckless.org/patches/font2/
Patch Link: https://st.suckless.org/patches/font2/st-font2-20190416-ba72400.diff

Additional notes:
This patch involved multiple steps:
+ libXft needs to be patched to avoid instant crash of st. The patch was
  submitted as a PR here
  (https://gitlab.freedesktop.org/xorg/lib/libxft/-/merge_requests/1)
  and here for the patch file
  (https://gitlab.freedesktop.org/xorg/lib/libxft/-/merge_requests/1/diffs.patch).
  Gentoo x11-libs/libXft package can be easily patched following the
  instructions here (https://wiki.gentoo.org/wiki//etc/portage/patches).
  A patched package is available in the AUR for ArchLinux users
  (https://aur.archlinux.org/packages/libxft-bgra/);
+ Install a font supporting colored emoji. In this case I prefer the
  Twitter Color Emoji font buy Joy Pixels (formerly EmojiOne) has been
  tested and works as well.
  Follow the instructions here to install the font
  (https://github.com/eosrei/twemoji-color-font#manual-install-on-any-linux).
  They also suggest to install Bitstream Vera font to use for
  serif/sans/sans serif fonts due to its (almost absent) coverage of
  emojis, which won't interfere with the emoji font.
  The installation script also deploys a fontconfig file to properly
  setup fonts. From initial tests seems to work out of the box;
+ Apply patch (manually)
