It also says they're "mapped".
If an implementation removes trailing spaces following a backslash in
translation phase 1, is that a "mapping"?
Here's the requirement (N1570 5.1.1.2p1):
Physical source file multibyte characters are mapped, in an
implementation-defined manner, to the source character set
(introducing new-line characters for end-of-line indicators)
if necessary. Trigraph sequences are replaced by corresponding
single-character internal representations.
One plausible interpretation of that is that each multibyte character
is replaced by a specific member of the source character set.
There could be a function that takes (some representation of) a
multibyte character as an argument, and returns a source character,
with that function being applied to each input character. Such an
interpretation would not permit mapping spaces to spaces in most
contexts, but mapping spaces to nothing at the end of a line.
I'm not saying that's the only correct interpretation.
