Pasting from InDesign

Does anyone know if copying text from an InDesign document and pasting it into the WP post editor will cause problems?

I know that pasting from word processors can cause trouble, but I don’t know about InDesign, and, as it would happen, I just found out that that is exactly what our editorial staff has been doing… for quite awhile. It makes me feel a little better that I am not aware of any problems caused by this, but it still worries me.
