Hope it helps
Thank you very much, but it did not work. I have found a way to do the job well. Just like below:

Your "solution" is dangerous. QString::fromUcs4() requires a NUL terminated UCS4 string if the length (second) argument is not specified. You are not providing a length or a NUL here. That it does not crash is just a happy coincidence.
QString str = QString::fromUcs4(&ui, 1);
Yes, you are right. I forgot the important argument. Thank you!
