Fontbakery Technical 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/outline_short_segments
- com.google.fonts/check/outline_colinear_vectors
- com.google.fonts/check/ttx_roundtrip
- com.google.fonts/check/version_bump
- com.google.fonts/check/outline_jaggy_segments
- com.google.fonts/check/outline_semi_vertical
- com.google.fonts/check/outline_alignment_miss
- com.google.fonts/check/fontdata_namecheck

OpenType Specification Checks

⚠️⏩⏩⏩⏩⏩⏩⏩ℹ️

Checking unitsPerEm value is reasonable.

Check ID: <FontBakeryCheck:opentype/unitsperem>
⚠️ BigShouldersInlineTextSC[wght].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 4000 instead.

Universal Profile Checks

🔥🔥⚠️⚠️⚠️⚠️⚠️⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩ℹ️ℹ️

Ensure the font supports case swapping for all its glyphs.

Check ID: <FontBakeryCheck:case_mapping>

Check ID: <FontBakeryCheck:math_signs_width>
⚠️ BigShouldersInlineTextSC[wght].ttf
