Well, for now, we've submitted a bug/feature request: 4501.

But actually, the point of my post was to determine what the current
behaviour is supposed to be.  You've confirmed the use of char*
everywhere, but that doesn't really address the encoding.  From our
tests, vtkTextActor only seems to support 7-bit ASCII, but vtkTextMapper
seems to support Latin1 (an 8-bit superset of ASCII with some accented
Latin characters, see <http://en.wikipedia.org/wiki/Latin1#Code_table>).

The docs don't say anything about which encoding is expected.  But I'm
definitely getting the feeling that 7-bit ASCII is all VTK likes. :(
