Doxygen, doxywizard encoding problem

I work under Windows XP and I'm using Doxygen (actually Doxywizard) to create documentation.

I have a problem with encoding. In Doxywizard's bookmark expert->proect->DOXYFILE_ENCODING I wrote cp1250 (I've tried also Windows-1250) but it still doesn't work and i do not get properly text.

I work in QtCreator.

Thanks for your help.
