2次曲線のremove overlap

Remove Overlap - Quadratic Curves - Glyphs - Glyphs Forum
ってことで、2次の場合のremove overlapは不完全っぽい・・・
少々アレだが以下のようにすればぼちぼち使えるかもしれない

font = Glyphs.font
for layer in font.selectedLayers:
    layer.removeOverlap(checkSelection=True)
    for path in layer.paths:
        path.convertToQuadratic()
    layer.roundCoordinates()
