I am using jQuery v1.7.1 in my Application. When I Use $.getJSON Function, it is getting failed when there are some special Characters. For example When I post a JSON Object like below

{ "aaData": [["","PLANNED ORDER","FAILED","---","79802","2012-10-19","MN_ORES_GEM_PE","M201","0001","GENERIC","50000","TO","Invalid Quantity Unit Code - TO ;"],["","PLANNED ORDER","FAILED","---","79803","2012-10-19","MN_ORES_GEM_PF","M201","0001","GENERIC","22500","TO","Invalid Quantity Unit Code - TO ;"]] }

I Am getting an error saying invalid JSON Object.

But When I remove the highlighted ";" from the JSON Object, the $.getJSON is working properly and returns a valid JSON Object.

I would like to know what are all the other special characters which are not aupported by JSON Object, so that I can avoid them. I would also like to know if there is any fix available for this issue....?
