# Emoji One Color SVGinOT 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.

## Examples
**Before**: Firefox in Ubuntu Linux.
[](images/before-linux-firefox.png?raw=true)
**After**: Firefox in all three operating systems, plus fall back outline
characters in the other browsers.
Some examples to see before and after on your machine:

* 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][6] and the [OpenType SVG table specifications][7].

## Install on Linux
The font can be installed for a user or system-wide. Get the latest version
from releases: https://github.com/eosrei/emojione-color-font/releases
Install for the current user only without root:
```sh
# 1. Download the latest version
wget https://github.com/eosrei/emojione-color-font/releases/download/v1.0-beta3/EmojiOneColor-SVGinOT-Linux-1.0-beta3.zip
# 2. Uncompress the zip file
unzip -o EmojiOneColor-SVGinOT-Linux-1.0-beta3.zip
# 3. Run the installer
./install.sh
```
*Warning: 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
`Emoji One Color` characters. The previous solution was to make
`Emoji One Color` the default system font, but that causes a number of issues
*(Check the issue queue.)* 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.
### 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.
### Arch Linux
An AUR is available: https://aur.archlinux.org/packages/emojione-color-font/
## Install on 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-1.0-beta2.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-1.0-beta2.zip` - A "hack" to replace the `Apple Color
Emoji` font by [using the same internal name][8]. Install and accept the
warning in Font Book.
3. `emojione-apple.ttf` - A bitmap Apple-format Emoji One color font is
[available in the emojione project][9].

[9]: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 on Windows
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][10]].

## 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
* SVGO
* [SCFBuild][11] *(created for this project!)*
* make
[11]: 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.* 😋
