Proposal: Should we replace vtkStdString with std::string

It stores a string that you can get/set in utf8 and utf16 encoding.

So vtkUnicodeString is a UCS4 string with conversion methods to/from UTF8/UTF16. The class name is ambiguous.

The problem is that if you just assume that char* and std::string is always UTF-8 encoded in VTK then it is hard to make sure that decoding/recoding happens correctly at all the interfaces (VTK / operating system, VTK / VTK-based third-party-libraries, VTK / application).
