Even though in principle, it's a nice thought that text encoding should
deal with semantics, it never has, and never will be, entirely.
The whole concept of writing is that it blurs the distinction between
form and function. The history of writing knows countless examples of
people just adapting existing visual signs (glyphs) to a fully different
meaning — it has been done with handwriting, and with typesetting. It
will never change.
The text encoding and the visual rendering must be "good enough" but
those standards vary. For some, there is no real difference between the
Latin A and the Cyrillic А (or was it A or maybe Α?). For others, there
is a functional difference between ‒ and –, so they have encoded them
separately, and yet, people key in 3–1 even if they mean 3‒1. (Erm, can
you see the difference here?).
As one friend once put it, "In Unicode, a character is an entity that is
defined by enumeration". John likes to quote Borges and his famous
"animal classification"*. In fact, the classification of writing marks
as "characters" vs. "glyphs" is just a splendid example of that very
After all, we're all still too lazy to key in the proper quotation marks :)

It doesn't change the meaning of the text whether that space is present
