Convert a irr::c8 to a wchar_t*

Question

I'm making a 3D environment, and I want to make it so that when you pass the crosshair over an object, some text with its description pops up. But I have this really annoying string format thing in the way.

  info.setText(CollMan->getSceneNodeFromScreenCoordinatesBB(blah)->getName());

info being the text object, and getSceneNodeblahblah->getName being the description that I want.

This doesnt work, because setText wants a wchar_t* and getName() provides an irr::c8. .c_str() doesn't seem to help whatsoever.

How can I get these two to play nice?

If I'm reading the docs correctly you ought to be able to do it by converting it to an irr::core::stringw first as follows:

info.setText( irr::core::stringw( CollMan->getSceneNodeFromScreenCoordinatesBB(blah)->getName() ).c_str() );
