SerenityOS Emoji Font

The SerenityOS pixel art emojis embedded in a TrueType font.

Installation & Usage

A nightly build of the font is done automatically via GitHub Actions, you can download it from here.

The font can be installed as a system wide font for emojis, used on a website, and more. The former will depend a lot on your operating system and desktop environment, an example for the latter can be found in the HTML file included in the archive mentioned above.

Please make sure to include a copy of the LICENSE file when distributing the font!

What's included?

Everything from /res/emoji, except for the private use area (PUA) emojis, which are mostly the yaks.

This means that non-standard emojis such as flags and ZWJ combinations (e.g. catdog) are included as well.

Building locally

Uses pixart2svg for vectorization of the emoji PNG images and nanoemoji to build the font. SVGs are cached, so subsequent runs of the build script will be much faster.

• Clone SerenityOS and export the path of your local checkout:

  export SERENITY_SOURCE_DIR='...'

• Install dependencies:

  pip install --user -r requirements.txt

• Download and patch pixart2svg:

  wget https://gist.githubusercontent.com/m13253/66284bc244deeff0f0f8863c206421c7/raw/f9454958dc0a33cea787cc6fbd7e8e34ba6eb23b/pixart2svg.py
  for file in patches/*.patch; do
    patch -p0 < "$file"
  done

• Build SerenityOS-Emoji.ttf:

  python main.py

The output files (TTF, index.html listing all included emojis) will be in build/.

TODO

This is an initial proof of concept that could be refined in multiple ways:

• Replace pixart2svg with something that is more flexible and doesn't need to be patched locally (it's GPL-licensed)
• Find a better approach for vectorization - the current solution of using adjacent SVG rects should in theory yield perfect results but has visible gaps between segments in reality, depending on the renderer and zoom level

This wouldn't be possible without all the awesome people creating & refining these emojis for the SerenityOS project! ❤
