I thought Notepad couldn't handle special character sets?
D'Oh! I've just realised that the way to get Notepad to recognise Russian is to tell windows (under the languages settings) that any non-Unicode text should be treated as Russian.
Presumably if I turn my Hanlin to the Russian language settings, it will also interpret non-Unicode text properly as Russian. It will also turn all my menus into Russian, but I think I can deal with that now!
I'm giving up converting text files to .DOC because I'm fed up of Word messing about with my ebook files. It tends to resize pages that I have carefully sized to fit my Hanlin.
