SVGinOT Color Font Builder
Create color fonts from SVGs on the command line
scfbuild creates SVG in OpenType color fonts directly from a set of source
SVG files greatly simplifying the process of creating a custom color font.
Regular color and standard character glyphs are named by Unicode code
1f60e.svg). Ligatures are named by code points separated
by a hyphen
1f441-1f5e8.svg). Note: Color glyphs cannot exist alone,
they must replace existing standard glyphs.
The generated fonts work in all operating systems, but will currently only show color glyphs in Mozilla Firefox and Thunderbird. This is not a limitation of the generated fonts, but of the operating systems and applications. Only the SVG in OpenType color font format is supported. The Apple, Google, and Microsoft color font formats are not supported.

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.

scfbuild softens the learning curve for font creation, but cannot replace more
advanced tools. Here are some starting points if you need more features,
although none support color fonts at this time:
