Windows-1251 character set

Aargh!  You hit a more common problem with interoperablity between os
and with national characters.  The only accurate solution for this I know
is to define some standard (like ascii was) dealing with intl chars,
for example, unicode, and to setup _all_ programs (ftp, browsers, archivers etc)
so them use that standard 8-(...

But for your particular ussue.
There are some routines in charcnv.c (you find them already)
that initializes charset conversation tables.  This probably should be
made as in charset.c (using external codepage files), but this requires
some thinking (again, maybe unicode can help here).
But in current situation you should define new mapping table to
translate characters coming from client to unix-side one and back.
I shure you know mapping between 866 and 1251 (OemToAnsiBuff() and
AnsiToOemBuff() if your locale in windows is set up properly).
So defining such a table is easy enouth.
Look to update_map() in charcnv.c.  It expects a string with pairs of
characters. First character is unix-side (strictly speaking server-side)
and second is client-side.  Remember that windoze will expect 866 charset
in server side, so you should convert it to 1251 on unix, and back -- 1251
to 866.  For example, russian letter A have code 0xc0 in 1251 and 0x80 in
866. You first pair is here: 0xc0 <=> 0x80.
So, init_windows_1251() should look like this:

static void init_windows_1251(int codepage) {
  and so on for all russian chars...

Note that you _should_ add "client codepage = 866" into your global section.
Or, better (?), add "if (codepage == 866) {" and "}" around update_maps calls...

And please sorry if this will not work -- maybe order should be opposite
(e.g. \0x80\0xc0 instead of \0xc0\0x80) :)

And do not forget to add call to your function to interpret_character_set(),
as this:
    } else if (strequal (str, "koi8-r")) {
    } else if (strequal (str, "windows-1251")) { /* official mime name */
and add "charset = windows_1251" to smb.conf.
