How can I figure out the Unicode code points supported by a Nerd Font?

[injust]

I tried using otfinfo --unicode ~/Library/Fonts/SymbolsNerdFont-Regular.ttf, but it exits 1 with otfinfo: bad table 1 length (format 12).

I'm not sure what you want to do.

Here is a list of the rough ranges: https://github.com/ryanoasis/nerd-fonts/wiki/Glyph-Sets-and-Code-Points
The codepoint of individual icons can be found there: https://www.nerdfonts.com/cheat-sheet
Checking if one specific codepoint is in which installed font: fc-list :charset=f000 (assuming you want to check u_F000)
Get a more or less conceise list of codepoints in the font file: fc-query --format='%{charset}\n' ~/Library/Fonts/SymbolsNerdFont-Regular.ttf

Never needed / even heard of otfinfo

Edit: Correct cheat sheet link

From ~/Library I guess you are on Mac. I have no clue what to use there, they do not have fontconfig (which are the commands starting with fc-)

fontconfig via Homebrew worked. Thanks for the answer!
