That is the existing solution for Emacs Lisp.  I'm looking
for a universal one.

For example.

For example in source blocks (#+BEGIN_SRC).

That would be the point; assuming a shell-script-mode buffer
with the text:

| ls 'string"literal""'

or a python-mode buffer with the text:

| print("string\"literal\"\"")

or a sql-mode buffer with the text:

| SELECT 'string"literal""';

or a perl-mode buffer with the text:

| print "string\"literal\"\"";

hitting C-c ' on any of those string literals would open a
new buffer with the text:

| string"literal""

where one could edit that string literal and hit C-c ' again
to replace the string literal in the original buffer.

(There are lots of edge cases where it is harder to DWIM,
but I'm fine with something that approximates the success
rate of Emacs's fontification.)
