I will just share my view on the whole problematic, trying to
concentrate more on the actual code look.
So I see it all as a chain of big steps, roughly:
1. One defines *the real code* or syntax, this means:
One takes a pen and a paper (photoshop/paint bucket)
and *defines* the syntax, this means one defines everything
as it is, including pixel precise spaces between operators,
punctuation and so on.
2. One develops an application (IDE) which enables you to
automatically load code file and (at least) view it
*exactly* as you have defined it.
3. Only after that one starts to think about ASCII/unicode/Hangul
(forgive me Lord) or whatever someone has defined as something
useful/standard.

So this actually would be a possible kind of "bridge" from the real code
to what is shown up in arbitrary text editing application or a mailing client.
In other words, you believe that in Unicode table you'll find something
useful for code definition, but I personally would not even start
relying on that, also because it is merely down-top problem solving.
