Safe strings

Passing strings verbatim to llJsonSetValue or llList2Json is not safe. One way to escape strings properly to make them safe for use with both is to use this function:

string String2Json(string s)
{
    return llGetSubString(llList2Json(JSON_OBJECT, [s,""]), 1, -5);
}

Examples:

llOwnerSay(String2Json(llUnescapeURL("%09"))); // outputs: Object: "\t"
llOwnerSay(String2Json("\n")); // outputs: Object: "\n"
llOwnerSay(String2Json("this \"string\" is not safe")); // outputs: Object: "this \"string\" is not safe"
llOwnerSay(String2Json("\"ab\"")); // outputs: Object: "\"ab\""

// Examples of use with the corresponding functions:
llOwnerSay(llJsonSetValue("[]", [0], String2Json("this \"string\" is not safe")));
llOwnerSay(llList2Json(JSON_ARRAY, [String2Json("this \"string\" is not safe")]));
// both output: Object: ["this \"string\" is not safe"]

Due to BUG-6495 this won't work. Nothing will. JSON is just broken.--Sei Lisa (talk) 07:27, 27 January 2015 (PST)
