Now I see what you mean.  Yes, they are clearly "visible" when you move
the cursor through them, in the sense that the cursor will jump.  (Does
this not happen in other text editors?)

Could we add some additional visual indication or warning for such
characters, in the light of this discussion?  I think there is a clear
risk that users will not step the cursor through some code they copied
from a website, or a patch with tens or hundreds of lines.  This means
that they might miss the indication that we have.
