Using a different character (namely =C2=A6) the following should work

#+source: clean
#+begin_src emacs-lisp :var in=3D""
  (flet ((clean (in)
                (if (listp in)
                    (mapcar #'clean in)
                  (if (stringp in)
                      (replace-regexp-in-string "=C2=A6" "|" in)
                    in))))
    (clean in))
#+end_src

#+results: regexps
| first  | (a=C2=A6b) |
| second | (1=C2=A62) |

#+begin_src perl :var a=3Dclean(in=3Dregexps)[0,1] :var b=3Dclean(in=3Drege=
xps)[1,1]
  $a; $b;
#+end_src

#+results:
: (1|2)
