Windows Chrome appears to be ignoring the kerning tables in the True Type files, as 'fox' appears fine (for me) on everything else I'm testing on. If I've missed something please let me know.
You will notice some issues if you use Windows Chrome, which doesn't render TTF well, particularly italics and obliques.
The fix for this is to include SVG font files. I excluded SVG as they're 'advertised' as only existing to support legacy iOS. Today I found out that's not entirely the case.
As for licensing, I provide the files for free for now and state on the site 'No attribution acquired'. I'm being vague because at this point I'm undecided whether to start selling it or not.
