Support for Russian encoding in the English Complete version of Heroes 3.

Sorry, I didn't notice it earlier: why are you playing the Russian version of "The Restoration of Erathia" instead of "The Shadow of Death" or "Complete Collection"? Do you like the bugs and the inability to play maps from "Armageddon's Blade" and "The Shadow of Death"? Naturally,

"The Restoration of Erathia" simply doesn't "see" this save file

because the versions are different, and the same applies to the maps.
