com.google.fonts/check/glyf_nested_components
[source][source]¶ Check glyphs do not have components which are themselves components.
Rationale:
There have been bugs rendering variable fonts with nested components. Additionally, some static fonts with nested components have been reported to have rendering and printing issues.

com.google.fonts/check/glyf_non_transformed_duplicate_components
[source][source]¶ Check glyphs do not have duplicate components which have the same x,y coordinates.
Rationale:
There have been cases in which fonts had faulty double quote marks, with each of them containing two single quote marks as components with the same x, y coordinates which makes them visually look like single quote marks.
This check ensures that glyphs do not contain duplicate components which have the same x,y coordinates.
