To me, when not using it to incorporate otherwise inaccesible characters,
the "\x{A0}" mechanism is useful primarily for disambiguation.
I use it regularly when I think it can contribute to clearer code, and in
such use it is directly analagous to the use of braces for disambiguation
of variables, as in "the ${word}s", or "${scalar}[0]".
