Yeah, suppose they could be as whitespace. Then we'd want to provide the 
same treatment for some other printer(system bell?) oriented encodings 
too if you go that route. Vertical-tab comes to mind & expect there are 
a few more.

Even in the old days it was printer dependent in terms of real world 
space(1) so not sure treating those special characters as something 
other than a single white space makes sense. I say this, though, not 
knowing what the POV-Ray windows editor does which such characters?

As for having these kind of characters in sample scene files we ship, 
suppose I'd argue they shouldn't exist. In my editor/font I get some odd 
fill-in character for it. I'm not sure what others might or might not see.
