That will solve only a small fraction of situations where these
characters are displayed, because the vast majority of them don't use
prin1 to produce a string to display.  Most of the stuff displayed by
Emacs doesn't come from strings produced by prin1, it comes from
displaying the text of some buffer.

So your proposal is incomplete at best.  Again, I already tried to
explain that several times.
