Extract QChar from QByteArray

harveyab

I have an iterator and for loop scanning a QByteArray.
I want to check for a valid UTF-8 character and extract it as a QChar at the current iterator position.
How do I do that?
Thanks.

@marceloarguello700 Sorry I didn't make it clear. I know what I would need to do it myself in code. I wondered if there was a function or member function to do it in one code statement. I would think this happens all the time, and I don't want to "re-invent the wheel."

Perhaps I should not have said UTF-8. I just want to "get" the QChar at the current position of the QByteArray. How do I access a possibly multibyte QChar from a QByteArray?

I know my reply is for old post,but this will helpfull for new people.

Below is the example code to filter UTF-8.I hope you will get resolution for your problem.

bool istextprintable(QByteArray text_temp){

QChar chrtr;
for(int i = 1; i < text_temp.size(); i++) {
chrtr = text_temp.at(i);
if((chrtr.isDigit() || chrtr.isLower() || chrtr.isUpper() || chrtr.unicode() == 0 || chrtr.unicode() == 32) == 0 ){

    return 0;
    }
}
return 1;

}

Untested

(as QDataStream might search for a special header)

// QByteArray byteArray;
QDataStream stream(byteArray);
QChar tempChar;
stream >> tempChar;
