FontBakery Check Report

If you think a check is flawed or have an idea for a check, please file an issue at https://github.com/fonttools/fontbakery/issues and remember to include a pointer to the repo and branch you're checking.

Summary

💥 ERROR	☠ FATAL	🔥 FAIL	⚠️ WARN	⏩ SKIP	ℹ️ INFO	✅ PASS
0	0	2	11	69	7	157
0%	0%	1%	4%	28%	3%	64%

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!)

⚠️ BungeeTint-Regular.ttf

⚠️ WARN

This check inspects the glyph outlines and detects the total number of contours in each of them. The expected values are infered from the typical ammounts of contours observed in a large collection of reference font families. The divergences listed below may simply indicate a significantly different design on some of your glyphs. On the other hand, some of these may flag actual bugs in the font such as glyphs mapped to an incorrect codepoint. Please consider reviewing the design and codepoint assignment of these to make sure they are correct.
