I've got an std::string content that I know contains UTF-8 data. I want to convert it to a QString. How do I do that, avoiding the from-ASCII conversion in Qt?

std::string s = "Übernahme"; QString q = QString::fromLocal8Bit(s. c_str()); If you don't have to deal with such strings, then the above answers will work fine.
std::wstring stemp = std::wstring(s. begin(), s. end()); LPCWSTR sw = stemp. c_str();
Using the stoi() function The stoi() function converts a string data to an integer type by passing the string as a parameter to return an integer value. The stoi() function contains an str argument. The str string is passed inside the stoi() function to convert string data into an integer value.
The c_str() and strcpy() function in C++ C++ c_str() function along with C++ String strcpy() function can be used to convert a string to char array easily. The c_str() method represents the sequence of characters in an array of string followed by a null character ('\0'). It returns a null pointer to the string.
QString::fromStdString(content) is better since it is more robust. Also note, that if std::string is encoded in UTF-8, then it should give exactly the same result as QString::fromUtf8(content.data(), int(content.size())).

There's a QString function called fromUtf8 that takes a const char*:
QString str = QString::fromUtf8(content.c_str()); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
