Check the direction of the outermost contour in each glyph

outline_direction

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

Rationale

In TrueType fonts, the outermost contour of a glyph should be oriented clockwise, while the inner contours should be oriented counter-clockwise. Getting the path direction wrong can lead to rendering issues in some software.
