Description

From TrueType Fundamentals:

The direction of the curves has to be such that, if the curve is followed in the direction of increasing point numbers, the black space (the filled area) will always be to the right.

Multiple icons break this convention. While most rasterizers will tolerate this out-of-spec behavior, sometimes (e.g., emboldening icons) this leads to artifacts. See uncharacteristically thin elements below.

Research direction

Start by identifying the affected icons from the linked image and compare their TrueType contours with the linked TrueType Fundamentals convention. Done means the affected contours follow the required direction and no longer produce the reported thin-element artifacts when emboldened.
