RFC 7159 describes JSON strings as follows: A string is a sequence of zero or more Unicode characters. To store objects in C++, a type is defined by the template parameters StringType which chooses the container (e.g., `std::string`) to use. Unicode values are split by the JSON class into byte-sized characters during deserialization. #### Default type With the default values for StringType (`std::string`), the default value for string_t is: std::string #### String comparison RFC 7159 states: Software implementations are typically required to test names of object members for equality. Implementations that transform the textual representation into sequences of Unicode code units and then perform the comparison numerically, code unit by code unit, are interoperable in the sense that implementations will agree in all cases on equality or inequality of two strings. For example, implementations that compare strings with escaped characters unconverted may incorrectly find that `"a\\\\b"` and `"a\\u005Cb"` are not equal. This implementation is interoperable as it does compare strings code unit by code unit. #### Storage String values are stored as pointers in a `basic_json` type. That is, for any access to string values, a pointer of type `string_t*` must be dereferenced.
