Detect Duplicate Contours

Is there anyway to detect this duplicate paths / contours?

Just saw Glyph Nanny which had this function (I realise “Tidy up paths” fixes most of these things too — though sometimes it cleans up ‘unnecessary points’ which I do need to have there for other processes involving interpolation)

There is a script for deleting duplicate paths in my Glyphs Scripts repository in GitHub. But generally, duplicate paths are no problem because they disappear by themselves when you remove overlaps at export.

Thats good to know, thanks!
