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.

DEPRECATION WARNING

By late-December 2024, FontBakery version 0.13.0 introduced a new naming scheme for the check-IDs.

Fontbakery detected usage of old IDs and performed an automatic backwards-compatibility translation for you.
This automatic translation will be deprecated in the next major release.

Please start using the new check-IDs as documented at /Lib/fontbakery/legacy_checkids.py

The following legacy check-IDs were detected:
- com.google.fonts/check/ttx_roundtrip
- com.google.fonts/check/outline_semi_vertical
- com.google.fonts/check/outline_alignment_miss
- com.google.fonts/check/fontdata_namecheck
- com.google.fonts/check/outline_colinear_vectors
- com.google.fonts/check/version_bump
- com.google.fonts/check/outline_short_segments
- com.google.fonts/check/outline_jaggy_segments

Summary

💥 ERROR	☠ FATAL	🔥 FAIL	⚠️ WARN	⏩ SKIP	ℹ️ INFO	✅ PASS
1	0	7	11	45	6	168
0%	0%	3%	5%	19%	3%	71%

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!)
