Invalid UTF-8 byte at index 1: 0x65

[hayalbaz]

• Describe what you want to achieve.
  I want to serialize an object that has a string with "Çevrimiçi" in it. When I try to j.dump() I am getting an exception (json.exception.type_error.316)
• Describe what you tried.
  I have tried to set compiler option /utf-8 and source/execution_charset to utf_8.
  I saved all my files with encoding utf-8
• Describe which system (OS, compiler) you are using.
  windows 10
  MSVC 19.20.27508
• Describe which version of the library you are using (release version, develop branch).
  latest release version

Can you provide example code? Is the string "Çevrimiçi" inside your code or do you read it from a file?

[hayalbaz]

Here is the function I am getting exception thrown:
std::string AliveLog::getJSON() { json j = json{ {"createdAt", createdAt}, {"id", id}, {"message", message}, {"detail", detail}, {"deviceId", deviceId}, {"type", type.ordinal}, }; return j.dump(); }
Here message is "Çevrimiçi". It is stored as std::string and is set by a setter method, which I use a struct that has std::string field..

It seems that the literal "Çevrimiçi" is not encoded in UTF-8. Can you try this:

for (int c : message)
{
    std::cout << "character: " << std::hex << c << std::endl;
}

to show the full encoded values in the string `message´?

If it's UTF-8, it should be something like

\xC3\x87\x65\x76\x72\x69\x6D\x69\xC3\xA7\x69

character : ffffffc7
character: 65
character: 76
character: 72
character: 69
character: 6d
character: 69
character: ffffffe7
character: 69

[hayalbaz]

When I define it like u8"Çevrimiçi" i get
character: ffffffc3
character: ffffff87
character: 65
character: 76
character: 72
character: 69
character: 6d
character: 69
character: fffffffc3
character: fffffffa7
character: 69

[hayalbaz]

However when i use j.dump() now the message is with different characters(A with ~ ın tıo and something that looks like a cross instead of Ç). I assume this is due to Visual Studio?

[nlohmann]

The u8 version looks right.

Do you need further assistance with this issue?

[hayalbaz]

No, thanks for asking. Weird characters at debug screen was a Visual Studio problem. It works fine now.
