Noto Emoji is a Unicode emoji font collection and SVG asset library designed to ensure consistent emoji rendering across different operating systems and web browsers. It functions as a color-font rasterization engine that embeds pre-rendered bitmaps into font files to display multicolored glyphs.
The project includes a variable-font emoji set that utilizes axes to adjust stroke thickness and style for both colorful and monochrome glyphs. It also maintains a Unicode emoji metadata registry that maps characters to shortcodes and ASCII equivalents.
The collection provides capabilities for color and monochrome emoji rendering, emoji asset extraction, and metadata mapping. These assets are generated from scalable vector graphics through a raster-based glyph pipeline.
