Russian bibliography files gost780s,gost71s generate incorrect TeX when used with Unicode, patch available

When running PDFLaTeX with UTF-8 documents and bibliography styles gost780s, gost71s with Russian letters in 'author' and 'title' fields - they produce incorrect UTF-8 symbols which are inserted at certain points (author's initials).

The fix is to change according .bst files, namely these lines should have f changed to ff:

FUNCTION {format.names}
{
  #1 "{vv~}{ll}{~jj}{,~ff.}" format.name$
}

FUNCTION {format.names.rev}
{ 's :=
  #1 'nameptr :=
  s num.names$ 'numnames :=
  numnames 'namesleft :=
    { namesleft #0 > }
    { s nameptr
      "{ff.}{~vv}{~ll}{, jj}"
