Something to think about, I have found that jsStringFormat misformats strings that contain single quotes and this breaks the json parsing that jquery uses (it's improper json so that is understandable). My trick is that I wrote my own wrapper around jsStringFormat that replaces "\'" back to "'" (backslash-single-quote back to single-quote).
I don't use remote cfc calls so I'm not sure your issue is the same jsStringFormat issue -- and if it is, I don't know how you would fix it!
