The following non-mark characters should not be in the GDEF mark glyph class:

• U+F6D4 (uni0306.cy)

The following glyphs are missing case-swapping counterparts:

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:

• uni04BC (U+04BC): found 3, expected one of: {1, 2}

Glyph uni04A1 has interpolation issues:

• Contour 0 becomes underweight in wght=700 compared to default

The most common width is 373 among a set of 13 math glyphs. The following math glyphs have a different width, though: width=387: logicalnot width=389: minus width=415: plusminus, notequal, equal, plus width=346: divide width=447: approxequal width=383: multiply

The stylistic set ss01 lacks a description string in the name table

fonts/variable/Oswald[wght].ttf: The following codepoints supported by the font are not covered by any subsets defined in the font's metadata file, and will never be served. You can solve this by either manually adding additional subset declarations to METADATA.pb, or by editing the glyphset definitions.
