No straightforward conversion will work, I'm afraid.

Sorry, I'm not following. This would be a new escape syntax for Elisp strings?
How would it work? For example, would \` and \' have different meaning in
strings than they do in character literals? When exactly would these escapes be
transformed to user-preferred quote characters? Although I have already
explored solutions along these lines and none of them worked well, perhaps you
have ideas that will improve them.
