cyryllic symbols

auto main( ) -> int
{
	setlocale(0, "ru");
	std::cout << nlohmann::json::parse(std::string("{ \"happy\": тест, \"pi\": 3.141 }")) << std::endl;
	Sleep(INT_MAX);
}

if I replace "тест" with English symbols, program doesnt throw an exception

The input to parse needs to be UTF-8. It is likely that the string that you're providing is not a valid UTF-8 string.

I compile with "/Zc:twoPhase- /utf-8"
And encoding is also set to Unicode

[nlohmann]

In your example, there are no quotes around тест. Does the code also fail with

auto main( ) -> int
{
	setlocale(0, "ru");
	std::cout << nlohmann::json::parse(std::string("{ \"happy\": \"тест\", \"pi\": 3.141 }")) << std::endl;
	Sleep(INT_MAX);
}

?

[eksponvt]

it works now but returns a weird value

[nlohmann]

Does your shell support UTF-8?

Could you try the following:

auto j = nlohmann::json::parse(std::string("{ \"happy\": \"тест\", \"pi\": 3.141 }"));
std::string j_dump = j.dump();

And then check in the debugger which bytes are stored in j_dump?

Can you please give the exact bytes stored (best as hex value)?

[eksponvt]

[nlohmann]

These bytes are UTF-8, so the library correctly parses and stores the string. Then it seems as if your system (shell, IDE, ...) does not correctly displays UTF-8.

For note, the C++ spec only allows for the lower ASCII range in source files, outside of that is extensions and is not technically proper/valid C++ (rather it is undefined behaviour, which some compilers may treat as expected, but it could do whatever).

However yeah, your terminal emulator is not displaying UTF-8 properly (it looks like it displays it as extended ASCII, not UTF-8).

@eksponvt Do you need further assistance?

No, thanks for help
