Description

Constant: string JSON_FALSE = "�";

The string constant JSON_FALSE has the value "�"

Return value for llJsonValueType function indicating the data type of a given address specifier in a given string-serialized JSON object.

Also used to set the bare word 'false' as a Value within a Json text using llJsonSetValue and llList2Json.
