You don't specify an encoding to be used when converting char* to a string
object. It will default to that defined by %DefaultEncoding. For Python3
PyQt sets this to ASCII, so either PyKDE is using %DefaultEncoding to
change the default, or its passing "-x Py_v3" to sip which will set
defaults for Python2 rather than Python3.
Note that there is a sip bug in generating the Python3 docstring for
unencoded char* where it generates "str" rather than "bytes".
