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	🔥 FAIL	⚠️ WARN	⏩ SKIP	ℹ️ INFO	✅ PASS
0	8	17	63	8	145
0%	4%	9%	33%	4%	76%

Note: The following loglevels were omitted in this report: SKIP, INFO, PASS, DEBUG

Meaning of check results:

💥 An ERROR is something wrong with FontBakery itself, possibly a bug.
🔥 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!)

PPEM must be an integer on hinted fonts.

Check ID: <FontBakeryCheck:com.google.fonts/check/integer_ppem_if_hinted>

🔥 RubikMonoOne-Regular.ttf

🔥 FAIL
This is a hinted font, so it must have bit 3 set on the flags of the head table, so that PPEM values will be rounded into an integer value.

This can be accomplished by using the 'gftools fix-hinting' command:
```
# create virtualenv
python3 -m venv venv
# activate virtualenv
source venv/bin/activate
# install gftools
pip install git+https://www.github.com/googlefonts/tools

Check if each glyph has the recommended amount of contours.

Check ID: <FontBakeryCheck:com.google.fonts/check/contour_count>

⚠️ RubikMonoOne-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:
