Twitter Color Emoji SVGinOT Font

A color and B&W emoji SVGinOT font built from the Twitter Emoji for Everyone artwork with support for ZWJ, skin tone diversity and country flags.

The font works in all operating systems, but will currently only show color emoji in Firefox, Thunderbird, Photoshop CC 2017, and Windows Edge V38.14393+. This is not a limitation of the font, but of the operating systems and applications. Why doesn't it work on Chrome? Regular B&W outline emoji are included for backwards/fallback compatibility.

What is SVGinOT?

SVG in Open Type is a standard by Adobe and Mozilla for color OpenType and Open Font Format fonts. It allows font creators to embed complete SVG files within a font enabling full color and even animations. There are more details in the SVGinOT proposal and the OpenType SVG table specifications.

Install on Linux

The font can be installed for a user or system-wide. Get the latest version from releases: https://github.com/eosrei/twemoji-color-font/releases

Note: This requires Bitstream Vera is installed and will change your systems default serif, sans-serif and monospace fonts.

Why Bitstream Vera

The default serif, sans-serif and monospace font for most Linux distributions is DejaVu. DejaVu includes a wide range of symbols which override the Twitter Color Emoji characters. The previous solution was to make Twitter Color Emoji the default system font, but that causes a number of issues. A better solution is a different font that doesn't override any emoji characters such as Bitstream Vera. Bitstream Vera is the source of the glyphs used in DejaVu, so it's not very different. 99%+ of people will not notice the difference.

Additional default font options

The Noto and Roboto font families conflict far less than DejaVu. You may want to try them. Primary issues are the 0x2639 and 0x263a characters.

Known issues

• Symbols/emoji in monospace formatted text cause incorrect character alignment. The whitespace character widths from the most recently selected fallback font are used in Pango/GTK applications.
• [Issue #31] Some font families are not matched correctly in Linux Firefox. Workaround: Open about:config set gfx.font_rendering.fontconfig.fontlist.enabled to false. Note: May cause crashes in Firefox <48.

Install on OS X

Both SVGinOT versions are available from releases: https://github.com/eosrei/twemoji-color-font/releases

1. TwitterColorEmoji-SVGinOT-13.0.1.zip - The regular version of the font installs like any other font and can be specifically selected, but OS X will default to the Apple Color Emoji font for emojis.
2. TwitterColorEmoji-SVGinOT-OSX-13.0.1.zip - A hack to replace the Apple Color Emoji font by using the same internal name. Install and accept the warning in Font Book.

A Homebrew package is available.

# Tap the caskroom/fonts keg, if needed.
brew tap caskroom/fonts
# Install the font using brew
brew cask install font-twitter-color-emoji

Reiterating: Only FireFox supports the SVGinOT color emoji for now. Safari and Chrome will use the fallback black and white emoji.

Install on Windows

There are two install options for Windows. Both SVGinOT versions are available from releases: https://github.com/eosrei/twemoji-color-font/releases

Standard install

The regular version of the font installs like any other font and can be specifically selected, but Windows will default to the Segoe UI Emoji font for emoji characters. Download: https://github.com/eosrei/twemoji-color-font/releases/download/v13.0.1/TwitterColorEmoji-SVGinOT-13.0.1.zip

Replace the default Windows emoji fonts

Windows 7, 8, 10 use emoji from both Segoe UI Symbol and Segoe UI Emoji. We need to replace both fonts, but keep the existing symbol characters from Segoe UI Symbol.

This package contains an install script that will generate both fonts (or in Windows 7, just Segoe UI Symbol) and install them for you. Running the install script requires both Python and pip in the PATH.

1. Download the most recent Python 3 for Windows: https://www.python.org/downloads/windows/
2. Start the installer, select "Add Python 3.6 to PATH", finish the install process, then reboot.
3. Download Twitter Color Emoji Windows package from releases: https://github.com/eosrei/twemoji-color-font/releases/download/v13.0.1/TwitterColorEmoji-SVGinOT-Win-13.0.1.zip
4. Uncompress the file.
5. Open the new TwitterColorEmoji directory.
6. Run install.cmd. Note: This will take some time.
7. Install both new fonts when requested.
8. Done!

Reiterating: Only FireFox and Edge (legacy) support the SVGinOT color emoji for now. Chrome and Edge (Chromium based) will use the fallback black and white emoji.

Uninstalling

There are uninstall scripts for Windows and Linux available. They are also included in the release files.

Building

Overview:

1. B&W SVGs are generated on-the-fly from the color SVGs
2. The B&W SVGs are imported based on their filename to create either regular glyphs or ligature glyphs.
3. The color SVGs are imported to override both types of glyphs.
