This is not the same. You may want to locally apply "errors=replace" and
not the whole program.

Indeed, this can silence encoding problems. So I would probably never
set in to errors at dev time except for the few places where I know I
can explicitly silence errors.

I quite like this print(errors="replace|ignore"). This is not going to
cause any trouble, and can only help.
