You could try to escape them, ('1//2') and ('/-')

Have you searched for it, this has been discussed several times?

The Cart library contains internal validation rules based on a regex, which unfortunately are (still) not documented. And afaik a regex failure doesn't generate an error message.

Look at the code which one you need, they are defined at the top of the class. Modify then after you've loaded the class, of extend it. I suggest you do not alter the core code.
