An open source font that you can’t see!
Adobe has announced the launch of Adobe Blank, which is an open source font that for a special purpose font came up when a few development teams asked the Adobe Type Team to produce a font that had all Unicode code points covered, and where all code points are rendered using a non-spacing and non-marking glyph.
The team soon realised that Adobe the right platform for developing such a font. The two major purposes of this font, according to developer Joel Brandt, are: font-fallback from kicking in before the intended font can be rendered. Related to this, using the font allows one to detect when a Web font is actually loaded, If it’s greater than zero, it has.
An example of a real-world use for Adobe Blank is the Adobe Edge Web Fonts extension for Brackets, which is available on GitHub.
Those who are interested can download the font from SourceForge and it will soon be on GitHub too.
