Colon in JSON string

Can I escape a colon : that is inside a JSON string? Currently this object/value set

{ pn: "MT46H128M16LFCK-5 IT:A", 
  visible: false, 
  url: "/$ws$/29/1/products/ProductDetails.html?product=products/dram/MT46H128M16LFCK-5 IT" 
}

doesn't get read. I suspect it's due to the :A in the pn value. How do I escape it or otherwise grab it?

If that's your actual JSON, your problem is that the identifiers (pn, visible, url), need to be quoted ("pn", "visible", "url").

As the comment said, colons don't need to be escaped in JSON string literals.
