With the vtkDataArray sublcasses, you can achieve this by doing a
DeepCopy between the arrays: all the values will be converted
automatically.  The string arrays do not support this auto-conversion
feature, however.  I'm not sure why they don't, but conversion from
strings to unicode is tricky because there are a lot of international
8-bit string encodings out there and it usually isn't safe to try and
guess which encoding is being used.
