Introduction
QByteArray is the Qt class to store a array of bytes. It is analogous to a char *. Unlike a QString, a QByteArray has no encoding information and makes no attempt to decode bytes into characters.
Converting QByteArray to QString
To convert a QByteArray to QString, one needs to specify the encoding. It is not possible to convert a QByteArray to QString without knowing the encoding. Once the encoding is known, one can use functions like QString::fromUtf8, QString::fromUcs4 or use QTextCodec::toUnicode().
QByteArray::fromRawData()
No copy. Copies point to raw data.
