Thanks Serge, that did fix the problem for this small demo project although it is not such a simple fix for a large project.
I'm guessing that when using controls with charset set to DEFAULT_CHARSET then if the software is running on a PC running Russian Windows then it should also work.
My concern is that I don't seem to have to do this for the rest of the components; only checkboxes and radio buttons.

Yes, your first examples with checkboxes works without problems on my russian PC.
