Set this as 'Block' since 0.18 will be py3 compliant.

I think this is a pivy problem. I guess SoAsciiString.text.setValues() should work with bytes-objects. Currently it works with unicode-objects (py3) but doesn't show special-symbols. Can anyone approve this assumption?

 I guess this is the relevant part where the problem occurs:


          arg4[i] = PyBytes_AsString(PyUnicode_AsEncodedString(item, "utf-8", "Error ~"));

No idea why swig creates this, as pivy defines the typemap in another way:

 This should fix the problem. The reason for the problem:

The c-function "PyObject_Str" is the same as "str" in python. Calling this function will convert any object to a unicode-object in python3. This results in things like "b'\xc2\abc...'"

edit: solves only http://forum.freecadweb.org/viewtopic.php?t=30824
the other 2 are still there, but should be easier to fix.
