Some modification to bgbg.c
I propose to replace ANSI_CHARSET to DEFAULT_CHARSET in bgbg.c to allow using of russian charsets (and any other? too) in installers screen/

CreateFont(40,0,0,0,FW_BOLD,TRUE,FALSE,FALSE,/bANSI_CHARSET/b,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH,"Garamond");

went like

CreateFont(40,0,0,0,FW_BOLD,TRUE,FALSE,FALSE,/bDEFAULT_CHARSET/b,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH,"Garamond");
