Style package for directly including color emojis in latex documents
TEXMFHOME=`kpsewhich -var-value TEXMFHOME`
mkdir -p ${TEXMFHOME}/tex/latex/local
cd ${TEXMFHOME}/tex/latex/local
git clone https://github.com/genericFJS/coloremoji.sty.git
You'll also need to generate emoji images. Grab one of
twemoji or
emojitwo; both contain SVG emojis. The
convert_svg-emoji_to_pdf.py script in the script/ directory can convert
these to PDF format for use with this package; it takes a path as an argument.
For instance using twemoji:
1. git clone https://github.com/twitter/twemoji.git
2. python3 convert_svg-emoji_to_pdf.py ../twemoji/svg
The script requires cairo installed locally (this is available in brew and
other package managers), as well as the cairosvg Python library, which can be
installed via pip.
The following LaTeX code:
\documentclass{article}
\usepackage{coloremoji}
\begin{document}
Hello, 🌎.
\end{document}
produces something like:
You can even use emojis in math. The following LaTeX code:
\[
🐊^{🐊^{🐊}} = ∫_{🎃} 🙊 \ d🍀
\]
produces something like:
This style sheet creates a PDF where each emoji is actually an embedded image rather than a character using the Apple Color Emoji typeface. This means you won't be able to correctly copy and paste emjois from the resulting .pdf files.
The encoding of the .tex must support emoji's, that is unicode characters. So switch your encoding to something like UTF-8.
