Here's MIT code that does that correctly. I ran into a font that would have like 3 OFF_CURVE points in a row and it rendered completely mangled. I checked OpenType.js.org and the had a glyph checker and it had different numbers of control points and resulting points. I hunted down the code from there.
It's a little weird but it fixes all the wonky text.

So the reason the shapes are wonky is that they are either all lines or quadratic bezier curves.

Less wonky inner-p contour.
