# Emoji One SVGinOT Color Font
A color and B&W emoji SVGinOT font built primarily from [Emoji One][1] artwork
with support for [ZWJ][2], [skin tone modifiers][3] and [country flags][4].
The font works in all operating systems, but will *currently* only show color
emoji in Mozilla Firefox and Thunderbird. This is not a limitation of the font,
but of the operating systems and applications. Regular B&W outline emoji are
included for backwards/fallback compatibility.

## Download
Go to [releases](https://github.com/eosrei/emojione-color-font/releases),
download the font zip file, install, and proceed with the instructions below for
your OS.
## Examples
**Before**: Firefox in Ubuntu Linux.
[](images/before-linux-firefox.png?raw=true)
**After**: Firefox in all three operating systems, plus fallback outline characters in the
other browsers.
Some examples to see before and after on your machine:
* http://eosrei.github.io/emojione-color-font/full-demo.html
* http://unicode.org/emoji/charts/emoji-zwj-sequences.html
* https://en.wikipedia.org/wiki/Regional_Indicator_Symbol
## 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][5] and the [OpenType SVG table specifications][6].
SVGinOT Demos (Firefox only):

* https://hacks.mozilla.org/2014/10/svg-colors-in-opentype-fonts/

[6]: https://www.microsoft.com/typography/otspec/svg.htm
## Install - Linux
The font can be installed and set as the default Emoji font system wide.
1. Get the latest release from: https://github.com/eosrei/emojione-color-font/releases
2. Uncompress the zip file
3. Double click the `ttf` file to open it in *Font Viewer*
4. Click the *Install Font* button
5. Create a font config directory:
```
mkdir -p ~/.config/fontconfig/
```
6. Override your defaults by creating a `~/.config/fontconfig/fonts.conf`:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!-- Make Emoji One Color the initial fallback font-->
<match>
<test name="family"><string>sans-serif</string></test>
<edit name="family" mode="prepend" binding="strong">
<string>Emoji One Color</string>
</edit>
</match>
<match>
<test name="family"><string>serif</string></test>
<edit name="family" mode="prepend" binding="strong">
<string>Emoji One Color</string>
</edit>
</match>
<match>
<test name="family"><string>monospace</string></test>
<edit name="family" mode="prepend" binding="strong">
<string>Emoji One Color</string>
</edit>
</match>
</fontconfig>
```
## Install - OS X
There are three install options for OS X. Both SVGinOT versions are available
from releases: https://github.com/eosrei/emojione-color-font/releases
1. `EmojiOneColor-SVGinOT.ttf.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.
2. `EmojiOneColor-SVGinOT-OSX.ttf.zip` - A "hack" to replace the `Apple Color
Emoji` font by [using the same internal name][7]. Install and accept the
warning in Font Book.
3. `emojione-apple.ttf` - A bitmap Apple-format EmojiOne color font is
[available in the emojione project][8].

[8]:https://github.com/Ranks/emojione/tree/master/assets/fonts
*Reiterating: Only FireFox supports the SVGinOT color emoji for now. Safari and
Chrome will use the fallback black and white emoji.*
## Install - Windows 10
The font installs like any other font and can be specifically selected, but
the system will default to the `Segoe UI Emoji` font.
It can be manually selected in CSS, but making it the default is still TBD.
## Known issues:
* VLC uses the system default Sans-Serif font for subtitles/OSD *without*
falling back for missing characters. Specifically select a subtitle/OSD font
[[details][9]].

## Building
The build process has only been tested on Ubuntu Linux.
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.
Required applications:
* Inkscape
* Imagemagick
* mkbitmap
* potrace
* FontTools
* FontForge
* [SCFBuild][10] *(created for this project!)*
* make
[10]: https://github.com/eosrei/scfbuild
Run: `make`
Or faster with multiple builds: `make -j 4`
*I am happy with the resulting outline glyphs, but there's room for improvement.
Let me know if you have ideas about making them look even better! I am not a
font building professional and only recently learned how to do all of this.* 😋
