Meaning of check results:
- 💥 An ERROR is something wrong with FontBakery itself, possibly a bug.
- ☠ A FATAL is an extremely severe issue that must be addressed immediately.
- 🔥 A FAIL is a problem with the font that must be fixed.
- ⚠️ A WARN is something that you should consider addressing.
- ℹ️ An INFO result simply prints something useful. Typically stats.
- ✅ A PASS means the font looks good for the given checking routine.
- ⏩ And a SKIP happens when the check does not apply to the given font.
If you get ERRORs, please help us improve the tool by reporting them at our issue tracker.
(but other kinds of bug reports and/or feature requests are also always welcome, of course!)
