Description
Constant: string JSON_NULL = "�";The string constant JSON_NULL has the value "�"
Return value for llJsonValueType function indicating the Json data type of a given address specifier in a given string-serialized JSON text.
Also the return string value for llJsonGetValue function when the bare word 'null' is at the given address specifier in a given string-serialized JSON text.
Also used to encode the bare word 'null' within a Json text to signify an empty, valueless placeholder Value at that location (the empty LSL String, "", can be used as well for that).
Caveats
