This should do it:

   qDebug("%s", ds.arg(glyph)
                .arg(log)
                .arg(xadvance)
                .arg(yadvance)
                .arg(xoffset)
                .arg(yoffset)
                .arg(QChar(lChar))
                .arg(hyphen.first.count())
                .toLocal8Bit().data());

The original version relied on the operator char *() overload of 
QByteArray, but that isn't applied in a vararg context.
