The idea behind REALGetStringData is that you want to get the string's
contents in an encoding that your code understands.
To give a real world example: we have a plugin internally that needs
to draw a string given to us by the user. Previously we would have had
to do an explicit encoding conversion, gotten the string's contents,
and then gone on with the work we actually cared about. The 'modern'
approach looks like this:
REALstringData title;
if (REALGetStringData( data->title, kTextEncodingUTF16LE, &title )) {
::DrawTextW( dc, (LPCWSTR)title.data, ... );
REALDisposeStringData( &title );
}
The sample projects that ship with the SDK may not have been updated,
so file a Feedback case if you see places where it needs changing.
