The separation of the nodes and the paths are now quite good IMHO, except some cases where the separation is over-made:







A solution to it is to change the default rectangle node shape





to something like this





Sorry, I am not good at drawing, especially drawing with a computer mouse.



In other word, I think I have to create a new TikZ node shape which depends on the maximum and the minimum "y-coordinates" of all characters.



It is way too complicated to me, and I haven't found a hint on this.



Can you help me? Any help is much appreciated.
