given that a syntax familiar to Emacs Lisp (and C) users is unavailable,
how would one accomplish the same goal: to embed a (named) control
character in a literal string in source code that is likely to travel
across all sorts of information-losing channels?

for an arbitrary character, either of the following forms produce the
desired result, but I find them clumsy.  do others do something else?

    #.(format nil "foo~Cbar" #\Newline)
    #.(concatenate 'string "foo" '(#\Newline) "bar")

(incidentally, my actual problem case involves lots of escape sequences for
a form printer now written in Emacs Lisp with the `cl' package.  it is
trivially portable to Common Lisp except for the string literals.)

I feel I must have overlooked something or think in the wrong terms.

Those who do not know Lisp are doomed to reimplement it.
