Problem displaying entity names

[Hatz~]

Hello, i'm trying to display monster names on a qt gui but there are some special characters like "á, é, í, ó, ú and ñ" that are not being displayed correctly, does anyone know how to fix it? I've tried to google for a solution but most of the things i've found are related to console changes.

Use different encoding

I've tryed using UTF-16 but it's displaying some random chinese characters

What you want to use is UTF-8

Uhm but isn't char strings already UTF-8? Sorry if this might looks like a very beginner question xD

Edit: so i've tried printing the names on a MessageBox and it was showing correctly there so the problem might be on the QString that is not on UTF-8 right? I've tried to use the method QString::fromUtf8() but didn't work

This is how im reading the char string:

MessageBoxA(NULL, mob->MonsterNamePtr->name, "", 0); // This shows correct name
ui->listWidget_2->addItem(mob->MonsterNamePtr->name); // This shows incorrect name

The strings in game are encoded with your default windows encoding (which is used by MessageBoxA), the QString operates on utf-8, you can use the QString::fromLocal8Bit to convert the native encoded char* to utf-8 QString

I managed to make it work aswell with QString::fromLatin1 but thanks anyways

Heya, now im trying to read/write stuff to a file and im facing the next issue, when i write to a file from a QString the entity name is being saved and displayed correctly on the file but when I read that same name from the file and try to convert it to a QString using QString::fromLatin1 or QString::fromLocal8Bit characters like "á, é, í, ó, ú" are not being displayed correctly.

Example of writing:

 Spoiler

std::ofstream ofile;

// Open the file for writing
ofile.open(filename.toStdString().c_str(), std::ofstream::out | std::ofstream::trunc);

// Error check
if (!ofile.is_open())
{
	MessageBoxA(NULL, "Failed saving the file.", "Error", MB_ICONERROR);
	return;
}

// Write to the file
// Imagine we have something like QString entityname = "Dánder"
ofile << entityname.toStdString();

// Close the file
ofile.close();

Example of reading:

 Spoiler

std::ifstream ifile;

// Open the file for reading
ifile.open(filename.toStdString().c_str());

// Error check
if (!ifile.is_open())
{
	MessageBoxA(NULL, "Failed loading the file.", "Error", MB_ICONERROR);
	return;
}

// Read the string
std::string name;
ifile >> name;
MessageBoxA(NULL, name.c_str(), "", 0);

// Close the file
ifile.close();

If someone can help me i'd be very thankfull

Why don't simply use the File-Class of QT?


(All untested)

    QFile file("out.txt");
    if (!file.open(QIODevice::WriteOnly | QIODevice::Text))
        return;

    QTextStream out(&file);
    out << "The magic number is: " << 49 << "\n";

Else try it with std::wstring instead of std::string.

QString sMyQtString = "test";

std::wofstream f(L"C:\\some file.txt");
f << sMyQtString.toStdWString();
f.close();

I didn't even know that Qt had that class . It worked very well ty for your help

Qt has everything you'll need. Really everything. Even 3D stuff / game rendering / Microcontroller etc... When I used it I never had one row with STD-library stuff.
