QByteArray to QString

I have a problem when converting QByteArray to QString and now I need a helper.

I have a file.txt contain "Công nghệ thông tin" :: it is a Vietnamese string.
I read file to byteArray (byteArray is a variable QByteArray type) .

Then, I convert it to string (string is a variable QString type).
code: QString string(byteArray);

But, occuring a error when display text "Công nghệ thông tin".
I think reason is encoding error.
I want a QString Utf8.

Please, help me, thanks. (sorry for my English level).

hi..
you can use this function below to convert to string.

public String Byte2Array(Byte[] b){
String str="";
for(int i=0;i<=b.length(),i++){
str = str + (char)byte[i];
}
print(str);
}

Do you need that byte array? or is it just for reading the file?

I suggest you to use QTextStream to read the file (with a proper encoding). Then you have the content in a QString which you can convert to a byte array if needed.

You should start your QByteArray with a unicode BOM, that way QString can detect the proper encoding correctly.

ketan007: That function is built into QString.
