QByteArray to QString
c++, qbytearray, qstring, qt, qtcore
Solution
You can use QTextCodec to convert the bytearray to a string:
QString DataAsString = QTextCodec::codecForMib(1015)->toUnicode(Data);
(1015 is UTF-16, 1014 UTF-16LE, 1013 UTF-16BE, 106 UTF-8)
From your example we can see that the string `"test"` is encoded as `"t\0 e\0 s\0 t\0 \0 \0"` in your encoding, i.e. every ascii character is followed by a `\0`-byte, or resp. every ascii character is encoded as 2 bytes. The only unicode encoding in which ascii letters are encoded in this way, are UTF-16 or UCS-2 (which is a restricted version of UTF-16), so in your case the 1015 mib is needed (assuming your local endianess is the same as the input endianess).
Problem
I'm having issues with `QByteArray` and `QString`. I'm reading a file and stores its information in a `QByteArray`. The file is in unicode, so it contains something like: `t\0 e\0 s\0 t\0 \0 \0` I'm trying to compare this value to my specified value, but it fails, because in the debugger I see it's not an unicode string. The code will explain everything: ``` QByteArray Data; //contains unicode string "t\0 e\0 s\0 t\0 \0 \0" QString myValue = "test"; //value to compare. if(Data.contains(myValue)) //do some stuff. else //do other stuff. ``` In the debugger, it shows me that the variable `Data` has the value `"t\0 e\0 s\0 t\0 \0 \0"` and `myValue` has the value `"test"`. How can I fix it?
