I don’t think there should be. This is for iconic fonts, where they put a bunch of useful “icons” in the private use area of of the Unicode code space, and then you can use those codepoints wherever you use text to get useful little icons.
The project linked here patches other fonts (including, presumably, those that have APL characters) to include these icons.
(Note that I don’t really like the use of icon fonts, but that’s neither here nor there…)
