But your reasoning is flawed: bascially you're saying some things are
already confusing, so it's just fine to add more confusion. It is not in
my opinion.

And that the computer can differentiate different characters is also
perfectly clear to me. The interpreter can also tell the difference
between a non-breaking space and a regular space. Yet the non breaking
space is not valid for a identifying character. This is because
readability counts.

People write and maintain code, not machines. Confusion should be kept
to the miminum if possible.

If that was written by my coworkers, I'd strangle them.
