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/outline_alignment_miss
- com.google.fonts/check/outline_colinear_vectors
- com.google.fonts/check/outline_jaggy_segments
- com.google.fonts/check/outline_short_segments
- com.google.fonts/check/ttx_roundtrip
- com.google.fonts/check/outline_semi_vertical
- com.google.fonts/check/version_bump
- com.google.fonts/check/fontdata_namecheck
Summary
💥 ERROR | ☠ FATAL | 🔥 FAIL | ⚠️ WARN | ⏩ SKIP | ℹ️ INFO | ✅ PASS |
---|---|---|---|---|---|---|
2 | 0 | 1 | 13 | 53 | 8 | 161 |
1% | 0% | 0% | 5% | 22% | 3% | 68% |
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!)

OpenType Specification Checks
⚠️⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩Checking unitsPerEm value is reasonable.
⚠️ Jersey10-Regular.ttf
-
⚠️ WARN
In order to optimize performance on some legacy renderers, the value of unitsPerEm at the head table should ideally be a power of 2 between 16 to 16384. And values of 1000 and 2000 are also common and may be just fine as well. But we got 1400 instead.

Check if each glyph has the recommended amount of contours.
⚠️ Jersey10-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.
The following glyphs do not have the recommended number of contours:
[code: contour-count]- Glyph name: dollar Contours detected: 2 Expected: 1, 3 or 5 - Glyph name: asterisk Contours detected: 5 Expected: 1 or 4 - Glyph name: comma Contours detected: 2 Expected: 1 - Glyph name: semicolon Contours detected: 3 Expected: 2 - Glyph name: cedilla Contours detected: 2 Expected: 1 - Glyph name: eth Contours detected: 3 Expected: 2 - Glyph name: aogonek Contours detected: 3 Expected: 2 - Glyph name: eogonek Contours detected: 3 Expected: 2 - Glyph name: uni0122 Contours detected: 3 Expected: 2 - Glyph name: uni013B Contours detected: 3 Expected: 2 - Glyph name: uni013C Contours detected: 3 Expected: 2 - Glyph name: uni0145 Contours detected: 3 Expected: 2 - Glyph name: uni0146 Contours detected: 3 Expected: 2 - Glyph name: uni0156 Contours detected: 4 Expected: 3 - Glyph name: uni0157 Contours detected: 3 Expected: 2 - Glyph name: Uogonek Contours detected: 2 Expected: 1 - Glyph name: uogonek Contours detected: 2 Expected: 1 - Glyph name: uni0218 Contours detected: 3 Expected: 2 - Glyph name: uni0219 Contours detected: 3 Expected: 2 - Glyph name: uni021A Contours detected: 3 Expected: 2 - Glyph name: uni021B Contours detected: 3 Expected: 2 - Glyph name: ogonek Contours detected: 2 Expected: 1 - Glyph name: uni0312 Contours detected: 2 Expected: 1 - Glyph name: uni0326 Contours detected: 2 Expected: 1 - Glyph name: uni0327 Contours detected: 2 Expected: 1 - Glyph name: uni0328 Contours detected: 2 Expected: 1 - Glyph name: quoteleft Contours detected: 2 Expected: 1 - Glyph name: quoteright Contours detected: 2 Expected: 1 - Glyph name: quotesinglbase Contours detected: 2 Expected: 1 - Glyph name: quotedblleft Contours detected: 4 Expected: 2 - Glyph name: quotedblright Contours detected: 4 Expected: 2 - Glyph name: quotedblbase Contours detected: 4 Expected: 2 - Glyph name: Uogonek Contours detected: 2 Expected: 1 - Glyph name: aogonek Contours detected: 3 Expected: 2 - Glyph name: asterisk Contours detected: 5 Expected: 1 or 4 - Glyph name: cedilla Contours detected: 2 Expected: 1 - Glyph name: comma Contours detected: 2 Expected: 1 - Glyph name: dollar Contours detected: 2 Expected: 1, 3 or 5 - Glyph name: eogonek Contours detected: 3 Expected: 2 - Glyph name: eth Contours detected: 3 Expected: 2 - Glyph name: ogonek Contours detected: 2 Expected: 1 - Glyph name: quotedblbase Contours detected: 4 Expected: 2 - Glyph name: quotedblleft Contours detected: 4 Expected: 2 - Glyph name: quotedblright Contours detected: 4 Expected: 2 - Glyph name: quoteleft Contours detected: 2 Expected: 1 - Glyph name: quoteright Contours detected: 2 Expected: 1 - Glyph name: quotesinglbase Contours detected: 2 Expected: 1 - Glyph name: semicolon Contours detected: 3 Expected: 2 - Glyph name: uni0122 Contours detected: 3 Expected: 2 - Glyph name: uni013B Contours detected: 3 Expected: 2 - Glyph name: uni013C Contours detected: 3 Expected: 2 - Glyph name: uni0145 Contours detected: 3 Expected: 2 - Glyph name: uni0146 Contours detected: 3 Expected: 2 - Glyph name: uni0156 Contours detected: 4 Expected: 3 - Glyph name: uni0157 Contours detected: 3 Expected: 2 - Glyph name: uni0218 Contours detected: 3 Expected: 2 - Glyph name: uni0219 Contours detected: 3 Expected: 2 - Glyph name: uni021A Contours detected: 3 Expected: 2 - Glyph name: uni021B Contours detected: 3 Expected: 2 - Glyph name: uni0312 Contours detected: 2 Expected: 1 - Glyph name: uni0326 Contours detected: 2 Expected: 1 - Glyph name: uni0327 Contours detected: 2 Expected: 1 - Glyph name: uni0328 Contours detected: 2 Expected: 1 - Glyph name: uogonek Contours detected: 2 Expected: 1
