I don't believe compilers do that in practice - the only observable
difference between raw literals and non raw literals in practice
is how universal-character-name *escape sequences* are handled (as well as
line splicing), the encodings involve are / should be the same
and the wording should be a better job at describing this intent as too
many destructive operations are done in phase 1 and 2

Strongly agree with all of that!
