Formats
There are multiple formats for emoji fonts, and not all of them work in the same way or be accepted by every operating system or device.
These are the formats you'll be able to compile your fonts into.
SVG-based formats
You need SVG images in your input to make these:
SVGinOT
Windows 10, macOS 10.14+, Linux, Firefox
This is a pretty inconsistent format and is currently not recommended for general use.
- SVG glyphs encoded as SVG tables
- OpenType ligature data
- .otf extension
PNG-based formats
You need PNG images in your input to make these.
The strikes for PNG-based formats are inferred from whatever is inside input folder.
sbixOT
Windows 10, macOS 10.7+, Linux
- PNG glyphs encoded as sbix tables
- OpenType ligature data
- .otf extension
sbixOTiOS
iOS 7+
sbixOT packaged in an iOS Configuration Profile. If you want your font to be installable on iOS, you need to build this.
You don't need to be using macOS to build one of these.
CBx
Windows 10, Linux, Rooted Android devices
- PNG glyphs encoded as CBDT/CBLC tables
- OpenType ligature data
- .ttf extension
This is specifically designed to mimic how Google encodes their emoji fonts.
'CBDT/CBLC' is more commonly used to refer to this format, but in forc it's simplified to 'CBx' to make it easier to remember.
