Hi,
I was recently confounded by this error and spent quite a while looking for unmached quotation marks, only to find out that my JSON had incorrect utf-8 data. Please take a look at the code sample below. I have a wrapper file for your library that looks like this:
namespace json {
using uint_t = std::uint64_t;
using int_t = std::int64_t;
using string_t = std::string;
template <typename T, typename... Args> using array_t = std::vector<T>;
template <typename K, typename T, typename... Args> using object_t = std::map<K, T>;
using bool_t = bool;
using float_t = double;
using Json = nlohmann::basic_json<object_t, array_t, string_t, bool_t, int_t, uint_t, float_t>;
}and here's an example program showing the issue:
#include "json-wrapper/json-wrapper.hpp"
int main(void) {
std::string data{};
data += char(0xff); // 'data' string is not UTF-8 compliant
json::Json message{};
message["data"] = data;
std::string raw_message = message.dump();
try {
json::Json parsed = json::Json::parse(raw_message);
}
catch (const std::exception& e) {
std::cout << e.what() << '\n';
}
return 0;
}The output is parse error - unexpected '"'. It should say that there was a problem parsing unicode characters.
