Type popping out of text frame

[Pickory]

#InDesign #typography Some times type pops out of the text frame, what is this called? Is there a way to detect or automatically fix it. Does it matter?

I have looked at the app.selection[0].lines[0].endHorizontalOffset, which seems to be clipped to the text frame.

It was suggested that I look at the optical settings, but these did not change the appearance.

If I export the frame the type is clipped.

Is this a bug?

*I have a motive this question, I have a plugin that can detect this effect. But, I would prefer a script.

Mark, that is very clever.  Excellent work.

Good to see a pure scripting solution.

Yes it's good. 
Would like it to duplicate the frame to a new layer and put all the markers on that new layer.

It would be simple layer deletion to remove all the other pieces around it.
