Font distibutors such as MyFonts, and publishers such as Linotype and FontFont, employ a system of icons to represent the features available in fonts.
These descend from the icons used in the GUIs of word processing and layout applications.
Noting that these icon systems are proprietary, I’ve recently made a set for my own use, in font format. However, it occurred to me that a standardized system might be useful for all concerned, especially to avoid confusion amongst those who come into contact with different ways of representing the same feature.
Is this a good idea, and if so, how could it be implemented, if at all?
