I doubt that Japanese would want it. I do use \N{IDEOGRAPHIC SPACE} a
bit as a *target* of regular expressions, but I would never want it as
non-syntactic in re.VERBOSE. (Of course, I'm not a native Japanese, but
I have never heard a Japanese developer wish for use of that character
in any programming language, outside of literal strings.)

That's a good question. Interpretation and display of R2L in
programming constructs came up briefly in the discussions about BIDI
on the emacs-devel list. I'll ask Eli Zaretskii, who implemented it
for Emacs.
