opentype__family__underline_thickness

Fonts have consistent underline thickness?

opentype/family/underline_thickness

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

Rationale

Dave C Lemon (Adobe Type Team) recommends setting the underline thickness to be consistent across the family.

If thicknesses are not family consistent, words set on the same line which have different styles look strange.
