There is a problem with encodeURIComponent:

After your server side script decoded the json data, it must make a “decodeURIComponent”.

Depending on what language you use, this could be a pain in the a**.

My suggestion is to use just:

—-

tData = tData.replace(/\\/g,'\\\\');

tData = tData.replace(/\”/g,'\\”');

ruleGroup += “\”data\”:\”” +
