Variable fonts are an extension to the opentype font format introduced in 2016, the new format allows to contain multiple font weights, widths and styles in a single font file.
Major operating systems and browsers all have support the variable fonts, like Windows 10 v1709+, MacOS 10.13+, Linux with FreeType 2.8, iOS 11, MIUI 11.
There are more and more variable fonts published by font vendors or font designers. You can find 56 varibale fonts in Google Fonts now.
So how about supporting them in Unity? It could be very helpful to create dynamic font assets.
Variable font support is something that I will be exploring in the future as they represent a nice saving on the file management side and build size given your only need a single font file for all font weights.
Same, any update? We just tried to implement a variable font and discovered Unity has zero support for it. Seems like a bit of an oversight considering more and more fonts are moving into variable fonts.
