Working with UTF-8 std::string objects in C++

I'm using Visual Studio and C++ on Windows to work with small caps text like ʜᴇʟʟᴏ ꜱᴛᴀᴄᴋᴏᴠᴇʀꜰʟᴏᴡ using e.g. this website. Whenever I read this text from a file or put this text directly into my source code using std::string, the text visualizer in Visual Studio shows it in the wrong encoding, presumably the visualizer uses Windows (ANSI). How can I force Visual Studio to let me work with UTF-8 strings properly?

std::string message_or_file_path = "...";
auto message = message_or_file_path;
// If the file path is valid, read from that file
if (GetFileAttributes(message_or_file_path.c_str()) != INVALID_FILE_ATTRIBUTES
 && GetLastError() != ERROR_FILE_NOT_FOUND)
{
 std::ifstream file_stream(message_or_file_path);
 std::string text_file_contents((std::istreambuf_iterator<char>(file_stream)),
 std::istreambuf_iterator<char>());
 message = text_file_contents; // Displayed in wrong encoding
 message = "ʜᴇʟʟᴏ ꜱᴛᴀᴄᴋᴏᴠᴇʀꜰʟᴏᴡ"; // Displayed in wrong encoding
 std::wstring wide_message = L"ʜᴇʟʟᴏ ꜱᴛᴀᴄᴋᴏᴠᴇʀꜰʟᴏᴡ"; // Displayed in correct encoding
}

I tried the additional command line option /utf-8 for compiling and setting the locale:

std::locale::global(std::locale(""));
std::cout.imbue(std::locale());

Neither of those fixed the encoding issue.

  • This may work for the text visualizer but it will not correct the code's encoding so it's only a semi solution. Still, you deserve your upvote. Commented Jan 31, 2020 at 22:45
  • @BullyWiiPlaza, what do you mean by the "the code's encoding"? Commented Jan 31, 2020 at 22:54
  • @R Sahu: I mean during processing of the code the string will not work correctly then. I e.g. copy the unicode text std::string object to the clipboard and when I paste it, it's screwed up. With a std::wstring version it works fine. Commented Feb 2, 2020 at 0:09
