Fontspector 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/fontspector/issues and remember to include a pointer to the repo and branch you're checking.

Summary

🔥 FAIL	⚠️ WARN	ℹ️ INFO	✅ PASS	⏩ SKIP
12	31	12	209	83
4%	9%	4%	62%	25%

Meaning of check results:

💥 An ERROR is something wrong with Fontspector 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!)

Fontspector version: 1.5.2

Opentype Specification Checks

Check that family axis ranges are identical

Check ID: opentype/varfont/family_axis_ranges

🔥 variable

🔥 FAIL
Variable axis ranges not matching between font files

The following values were found:
- wght=100.00:400.00:700.00: UbuntuSansMono[wght].ttf
- wght=400.00:400.00:700.00: UbuntuSansMono-Italic[wght].ttf
[code: axis-range-mismatch]

Check glyphs in mark glyph class are non-spacing.

Check ID: opentype/GDEF_spacing_marks

⚠️ UbuntuSansMono[wght].ttf

⚠️ WARN
The following glyphs seem to be spacing (because they have width > 0 on the hmtx table) so they may be in the GDEF mark glyph class by mistake, or they should have zero width instead:
- tonos.cap
[code: spacing-mark-glyphs]

Checking correctness of monospaced metadata.

Check ID: opentype/monospace

⚠️ UbuntuSansMono[wght].ttf

⚠️ WARN
The OpenType spec recommends at https://learn.microsoft.com/en-us/typography/opentype/spec/recom#hhea-table that hhea.numberOfHMetrics be set to 3 but this font has 1713 instead. Please read https://github.com/fonttools/fonttools/issues/3014 to decide whether this makes sense for your font.

Universal Profile Checks

Ensure that all variable font files have the same set of axes and axis ranges.

Check ID: varfont/consistent_axes

🔥 variable

🔥 FAIL
Font fonts/variable/UbuntuSansMono-Italic[wght].ttf has inconsistent range for axis wght: expected [100, 700], found [400, 700]
[code: inconsistent-axis-range]

Check accent of Lcaron, dcaron, lcaron, tcaron

Check ID: alt_caron

⚠️ UbuntuSansMono[wght].ttf

Check if each glyph has the recommended amount of contours.

Check ID: contour_count

⚠️ UbuntuSansMono[wght].ttf

⚠️ WARN
This check inspects the glyph outlines and detects the total number of contours in each of them. The expected values are inferred from the typical amounts 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:
```
- zero.osf (unencoded): found 3, expected one of: {2}
- uni2612 (U+2612): found 4, expected one of: {6, 3, 5}
