contour_count

Check if each glyph has the recommended amount of contours.

• Applies to: TTF
• Fontspector can hotfix?: no
• Fontspector can fix sources?: no

Rationale

Visually QAing thousands of glyphs by hand is tiring. Most glyphs can only be constructured in a handful of ways. This means a glyph's contour count will only differ slightly amongst different fonts, e.g a 'g' could either be 2 or 3 contours, depending on whether its double story or single story.

However, a quotedbl should have 2 contours, unless the font belongs to a display family.

This check currently does not cover variable fonts because there's plenty of alternative ways of constructing glyphs with multiple outlines for each feature in a VarFont. The expected contour count data for this check is currently optimized for the typical construction of glyphs in static fonts.
