latin1 / utf8

[Wolfram Lyda]

In some cases the PyUnicode_FromString()-Method should be changed to PyUnicode_DecodeLatin1() if QString.toLatin1().data() should be converted to avoid special-character errors.

This changes need some more elaborated testings

[Wolfram Lyda]

Changed most entries to PyUnicode_FromUnicode. Python uses UFT8, Qt uses latin1.

Tested for several month, seems working, marked as resolved
