# Emoji One SVGinOT Color Font
A color and B&W emoji SVGinOT font built primarily from [Emoji One][1] artwork
with full 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 Emoji are included
for backwards/fallback compatibility.

## What is SVGinOT?
*SVG in Open Type* is the new standard by Adobe and Mozilla for color OpenType
and Open Font Format fonts [adopted by the W3C on January 27th 2016][5]. 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][6]
and the [OpenType SVG table specifications][7].

## Examples
## Usage - Linux
The font can be installed and set as the default Emoji font system wide.
1. Store the font file in your `~/.fonts/` directory.
2. Create a font config directory:
```sh
mkdir -p ~/.config/fontconfig/
```
3. Override your default by creating a `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>
```
## Usage - OS X
The font installs like any other font and can be specifically selected, but
the system will default to the `Apple Color Emoji` font. If wanted, change the
default by disabling the original:
```sh
cd /System/Library/Fonts/
sudo mv Apple\ Color\ Emoji.ttf Apple\ Color\ Emoji.ttf-old
```
*Reiterating: Only FireFox supports the color emoji for now. Safari and Chrome
will use the fallback black and white emoji.*
## Usage - 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.
## 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 (created for this project!)
* make
Run: `make`
Or faster with multiple builds: `'make -j 4`
*I am happy with the resulting glyphs, but if you have ideas about making
them look even better let me know! I am not a font building professional and
only recently learned how to do all of this.* 😋
