basic_json::error_handler_t

enum class error_handler_t {
    strict,
    replace,
    ignore
};

This enumeration is used in the dump function to choose how to treat decoding errors while serializing a basic_json value. Three values are differentiated:

strict
throw a type_error exception in case of invalid UTF-8
replace
replace invalid UTF-8 sequences with U+FFFD (� REPLACEMENT CHARACTER)
ignore
ignore invalid UTF-8 sequences; all bytes are copied to the output unchanged
