When the character you want to describe is covered by an overlay, `describe-char' always creates a dummy overlay of length 1 at that position and gives it the properties of the overlay covering the character you want to describe. In your case there must have been at least one overlay covering the space. Any overlay properties there should have been replicated correctly. The `From 14 to 15', however, refers to the dummy overlay in the *Help* buffer and should be, in my opinion, omitted. Obtaining the start/end positions of all overlays covering the character you want to describe would require a revision of the concept sketched above.
