That happens in the shell. You can do this to start your session:

#+BEGIN_SRC shell :session mysess
   PS1="MyPrompt-$ "
#+END_SRC

#+RESULTS:

and then tell emacs to locally set `comint-prompt-regexp' to a value
other than what was copied from `shell-prompt-pattern'

#+BEGIN_SRC emacs-lisp
   (save-excursion
     (pop-to-buffer "mysess")
     (setq-local comint-prompt-regexp "MyPrompt-$ "))
#+END_SRC

#+RESULTS:
: MyPrompt-$

and then it should work.

#+BEGIN_SRC shell :session mysess
   echo "a%b"
#+END_SRC

#+RESULTS:
: a%b

---

You might skip the second step and instead set `shell-prompt-pattern'
to "MyPrompt-$ ". If `comint-use-prompt-regexp' is nil, then the
`comint-prompt-regexp' is only consulted by ob-shell.el funs per the 
docstring of comint-use-prompt-regexp.
